The most common form of system memory packaging. DRAM can hold a charge (that is, data) for only a short period of time. Therefore, to retain the data it must be refreshed periodically. If the cell is not refreshed, the data is lost.
DRAMs are among the most commonly used semiconductors and are used for information storage in a large number of personal computers. In 2001, the global DRAM market shrank by 60% to about 11 billion dollars due to the information technology slump. However, demand has been slowly recovering since the end of 2001. In 1997, 16-megabit DRAM chips were gradually replaced by high-speed 64-megabit chips, and shipments of much-faster 256-megabit chips started in 2000. Each technological improvement costs manufacturers hundreds of billions of yen. As a result, the competitiveness of a manufacturer largely depends on its investment reserves, which in turn are closely related to the size of its operations.
Dynamic RAM A type of memory that has to be refreshedregularly or the data will be "forgotten". Single accesses tends to be slower than SRAM, but DRAM has lower power consumption and is cheaper. Can usually use a burst mode to improve performance. The synchronous version, S DRAM, is the type of memory installed in PCs.
ynamic andom ccess emory. It is a kind of memory chip in which data is stored capacitively and which must be energized or recharged hundreds of times a second or the data will be lost. While DRAM is being refreshed, it cannot be read by the processor. If the processor attempts to read the DRAM while it is being refreshed, one or more wait states occur. DRAMs offer high bit densities, low cost, input/output compatibility with TTL levels, and speed compatibility with most microprocessors. The operational speed of DRAM chips is measured in nanoseconds, such as 100, 80, and 70ns.
Dynamic RAM is typically the RAM used as the main memory in a computer system. DRAM requires fewer transistors per bit than SRAM, but each bit needs to be refreshed regularly or it will lose information. DRAM is typically slower but much less expensive than SRAM.
Dynamic Random Access Memory (see also SDRAM). A type of memory used in a PC for the main memory (such as your "32 Mbytes of RAM".) "Dynamic" refers to the memory's memory of storage - basically storing the charge on a capacitor. Specialized types of DRAM (such as EDO memory) have been developed to work with today's faster processors.
( ynamic andom ccess emory) - The most common type of computer memory. DRAM can be made very inexpensively compared to other types of memory. DRAM chips are small and inexpensive because they normally require only one transistor and a capacitor to represent each bit. The capacitors must be energized every 15ms or so (hundreds of times per second) to maintain their charges. DRAM is volatile, meaning it will lose data with no power or without regular refresh cycles.
DRAM (dynamic random access memory) is most commonly used type of memory in computers. A bank of DRAM memory usually forms the computer's main memory. It is called Dynamic because it needs to be refreshed.
dynamic random access memory. The readable/writable memory used to store data on the platform. Must be continually refreshed due to its inability to store data longer than a few milliseconds. However, the chips are relatively inexpensive to manufacture and so are worth managing.
Dynamic Random Access Memory is one type of chip used in Random Access Memory. It stores information as an electrical charge. Because this charge dissipates over time, the computing device must periodically run a "refresh cycle" on the chips to recharge them – hence "dynamic". As it is a type of RAM, it will lose its information when the device into which it is installed is turned off. Typically, the time required to access information with a DRAM scheme is greater than with SRAM. SRAM chips can also not be substituted for DRAM chips; the machine (e.g. printer) must have been designed to use SRAM.
The most common and cheapest form of computer memory, which uses one capacitor and transistor to store one bit of information. It is 'volatile' memory, so if you turn off the power you will lose any stored data.
Dynamic random access memory (DRAM) is the most common kind of random access memory (RAM) for personal computers and workstations. memory is the network of electrically-charged points in which a computer stores quickly accessible data in the form of 0s and 1s. Random access means that the PC processor can access any part of the memory or data storage space directly rather than having to proceed sequentially from some starting place. DRAM is dynamic in that, unlike static RAM (SRAM), it needs to have its storage cells refreshed or given a new electronic charge every few milliseconds.
DRAM (Dynamic Random Access Memory) is the most common type of memory and is "dynamic" because in order for the memory chip to retain data, it must be refreshed constantly (every few milliseconds). If the cell is not refreshed, the data is lost. DRAM temporarily stores data in a cell composed of a capacitor and a transistor. Each cell contains a specified number of bits. These cells are accessed by row addresses and column addresses.
(Dynamic Random Access Memory) The most common form of RAM. DRAM can hold data for only a short time. To retain data, DRAM must be refreshed periodically. If the cell is not refreshed, the data disappear.
(Dynamic Random Access Memory) memory that consists of small capacitors for each bit of memory. Since capacitors do not hold a charge indefinitely, DRAM must be constantly refreshed to avoid losing its contents. Also, the process of reading the contents of the memory are destructive, meaning extra time must be spent restoring the contents of memory addresses which are accessed, so DRAM is slower than SDRAM
Pronounced “dee-ram.” The readable/writable memory used to store data in personal computers. DRAM stores each bit of information in a “cell” composed of a capacitor and a transistor. Because the capacitor in a DRAM cell can hold a charge for only a few milliseconds, DRAM must be continually refreshed in order to retain its data. Static RAM, or SRAM, requires no refresh and delivers better performance, but it is more expensive to manufacture. See also EDO RAM and SRAM.
Dynamic Random Access Memory is a type of memory component. " Dynamic" means the device's memory cells must be recharged periodically. Information stored in the memory cells is accessed randomly. Memory is a key component of most electronic products.
(Pronounced DeeRam). Dynamic Random Access Memory. The memory of a computer into which the software is loaded prior to execution by the CPU. Needs periodic refreshes to avoid loss of data. Measured in units of bits.
( ynamic RAM) is a widely available, very affordable form of RAM that has the unfortunate tendency to lose data if it is not recharged regularly (every few milliseconds). This refresh requirement makes DRAM slower by a factor of three to ten compares to non-recharged RAM such as SRAM.
Dynamic Random Access Memory. A memory chip that uses capacitive techniques for storing data. This method requires constant refresh cycles every second to maintain data integrity. During the refresh the processor cannot read data and is forced to wait.
A type of semiconductor memory, dynamic random access memory. DRAMs account for a significant percent of the total semiconductor market (between 15 and 30%) and so DRAM manufacturers are big equipment buyers. DRAM manufacturing is concentrated in Japan and Korea.
This stands for Dynamic Random Access Memory, the most common form of RAM, or random access memory. It can only hold data for a very short period of time and since it is dynamic, it needs a constant refresh to keep the stored information.
(dee-ram) Dynamic Random Access Memory. RAM that requires external refresh circuitry and a minimum clock speed to retain its state. If dynamic RAM loses power, all its little capacitors discharge and it forgets everything. Compare SRAM.
Abbreviation for dynamic random-access memory. A system's RAM is usually made up entirely of DRAM chips. Because DRAM chips cannot store an electrical charge indefinitely, your system continually refreshes each DRAM microprocessor in the system.
Dynamic Random Access Memory. The most common type of system RAM. It comes in several different flavors, EDO, FPM, SDRAM. It uses less space, less power, and is cheaper than static RAM, but it has to be refreshed every millisecond or it loses its information.
Dynamic Random Access Memory. A low-cost, read-write memory where data is stored on capacitors and must be refreshed periodically. DRAMs are usually addressed by a sequence of two addresses, row address and column address, which makes them slower and more difficult to use than SRAMs.
An acronym for Dynamic Random Access Memory. A type of memory chip that only keeps its memory if supplied with regular clock pulses and a chance to regularly refresh its data. It is slower and more cost effective than SRAM. See SRAM.
Abbreviation for dynamic random-access memory. A computer's RAM is usually made up entirely of DRAM chips. Because DRAM chips cannot store an electrical charge indefinitely, your computer continually refreshes each DRAM chip in the computer.
(pronounced "DEE ram"). Dynamic RAM. From a user's point of view, RAM is RAM - it doesn't matter what type it is. Technically, DRAM is dense (more bits per cubic centimeter), but slow because it requires clocking to get data out. It is one of two types of RAM in your 01.
Dynamic Random Access Memory. A memory IC that must have power on and must also be refreshed periodically to maintain correct data (Dynamic). Data stored in the memory can be accessed randomly (Random Access). All DRAMs have multiplexed addressing.
Dynamic random access memory. A type of memory component used to store information in a computer system. "Dynamic" means the DRAMs need a constant "refresh" (pulse of current through all of the memory cells) to keep the stored information. (See also RAM and SRAM.)
A type of semiconductor memory in which the information is stored in capacitors on a MOS integrated circuit. Typically each bit is stored as an amount of electrical charge in a storage cell consisting of a capacitor and a transistor. Due to leakage the capacitor discharges gradually and the memory cell loses the information. Therefore, to preserve the information, the memory has to be refreshed periodically. Despite this inconvenience, the DRAM is a very popular memory technology because of its high density and consequent low price.
Dynamic Random Access Memory. A semiconductor read/write memory chip, in which the presence or absence of a capacitive charge represents the state of a binary storage element (zero or one). The charge must be periodically refreshed.
Abbreviation for dynamic random access memory. A type of RAM that stores information in integrated circuits containing capacitors. Since capacitors lose their charge over time, DRAM boards include logic to recharge, or "refresh," the RAM chips continuously. Since their internal circuitry is simple, DRAMs are more commonly used than static RAMs, even though they are slower. DRAM can hold approximately four times as much data as a static RAM chip of the same complexity. The reader has 1MB of battery-backed DRAM.
Dynamic Random Access Memory, a memory technology which is periodically "refreshed" or updated – as opposed to "static" RAM chips which do not require refreshing. The term is often used to refer to the memory chips themselves. Varieties are: CDRAM Cache DRAM (contains static cache) EDODRAM Extended data out DRAM EDRAM Enhanced DRAM (contains a static memory buffer and cache controller) SDRAM Synchronous DRAM (added clock and burst addressing capability) SGRAM Synchronous Graphics RAM (a single port SDRAM) WRAM Window RAM (dual port video RAM) VRAM Video RAM (a dual ported DRAM, good for graphics).
(dee ram) abbr. A type of RAM that maintains its content only as long as the data stored in the device is refreshed at regular intervals. Short for Dynamic Random Access Memory. The repetitive row by column refresh access cycles are usually performed by a peripheral called a DRAM controller. If this isn't done every few milliseconds, some or all of the data stored in the memory can be lost. DRAM is much cheaper per byte than SRAM because it requires just one transistor per bit rather than four to six; however, it has longer access times. DRAM's lower cost per byte makes it attractive whenever large amounts of RAM are required. Many systems include both types: a small block of SRAM (a few kibi bytes) along a critical data path and a much larger block of DRAM ( mebi bytes perhaps) for everything else. [ more
A measure of Scotch whisky of unspecified size, although in some Scottish bars a 'dram' is taken to mean a large or double whisky. 'Dramming' in distilleries was the semi-official practice of offering employees amounts of spirit at regular intervals during the working day. The advent of drink driving laws and 'health and safety' legislation finally ended the custom.
The dram (archaic spelling drachm) was historically both a coin and a weight. Currently it is both a small mass in the avoirdupois system of weights and a small unit of volume. This unit is called more correctly fluid dram or in contraction also fluidram.
