A high-speed, buffer-type memory filled at medium speed from the main memory. [Programs and instructions found in the cache memory can be operated at higher speeds without the necessity of loading another segment.
Also known as cache RAM; a small, high-speed memory device located between the CPU and the system DRAM. Cache is designed to supply the processor with the most frequently requested instructions and data. Cache memory can be three to five times faster than system DRAM.
Specialized RAM used to optimize data transfers between system elements with different performance characteristics, e.g., disk to main memory or main memory to CPU. Having certain data stored in cache speeds up the operation of the computer. There are two kinds of cache: internal (or memory cache) and external (or disk cache). Internal cache is built into the CPU, and external cache is on the motherboard. When an item is called for, the computer first checks the internal cache, then the external cache, and finally the slower main storage.
Frequently used data and programs are stored in this temporary memory. Before executing a command, the CPU accesses this memory first for instructions or data.
a small, fast, redundant memory used to store the most frequently accessed parts of the main memory. [SILC99
Cache RAM is fast random-access memory that is used to store data for CPU operations. Level 1 cache RAM is part of the CPU itself; level 2 L2 cache RAM is on separate chips. Conventional L2 cache is connected to the system bus, and the speed of its transactions with the CPU is limited by the system bus speed. Level 2 backside cache a feature introduced with G3 computers is located on the same board as the CPU processor board and is connected directly to the CPU through its own high-speed bus. The L2 backside cache allows the system to run significantly faster than conventional L2 cache. As more and more processors begin to include L2 cache into their architectures, Level 3 cache is now the name for the extra cache built into motherboards between the microprocessor and the main memory-what was once L2 cache on motherboards now becomes L3 cache when used with microprocessors containing built-in L2 caches.
A specialized chip used with the computer's memory to provide a storage area that keeps frequently used accessed data or program instructions readily available.
The area of memory that stores the most recently accessed data. When a computer needs data once, chances are it will need it again, soon, so computer designers realized they could speed up the computer by storing the most recently accessed data in a high-speed storage area. Most caches are FIFO (first in, first out). This means that as the cache fills, the older data is thrown out. This makes sense because you want the most recently accessed data available. There are several types of cache on your computer, including application cache, disk cache, hardware cache, and processor cache.
is where instructions and information wait for processing after they arrive in the CPU from RAM.
A small block of high-speed memory (usually SRAM) located between the CPU and main memory that is used to store frequently requested data and instructions. Properly designed, a cache improves system performance by reducing the need to access the system's slower main memory for every transaction.
A small, high-speed buffer memory used in modern computer systems to hold temporarily those portions of the contents of the main memory that are, or believed to be, currently in use.
Cache memory supports write-through or write-back caching, which can be selected for each logical drive. To improve performance in sequential disk accesses, the HP RAID 4Si controller uses write-through caching by default. You can disable write-through caching. With the battery pack, the cache memory provides up to 72 hours of data protection in the event of a power failure.
a small but very fast memory used to store frequently used Data or instructions
a small, fast memory, ideally into which the address space of a running program is held in order to improve efficiency
a small memory close to (or on) a microprocessor that stores recently used data on the valid premise that if the microprocessor has needed certain data recently, it is likely to need it again in the immediate future
A group of fast memory chips located on or near the CPU to help speed up processing.
High-speed, buffer-type computer memory used for storage of frequently used instructions or data.
is a mechanism interposed in the memory hierarchy between main memory and the CPU to improve effective memory transfer rates and raise processor speeds. The name refers to the fact that that the mechanism is essentially hidden and appears transparent to the user.
simply called "cache". Part of a computer's RAM operating as a buffer between the system RAM and CPU. Recently used data or instructions are stored in cache. RAM is accessed quickly, so data called for again is available right away. This functionality improves overall system performance.
This is costly high speed memory built into: computer motherboards, hard drives motherboards, processors, CD Drives etc it is used as a high speed data buffer to accelerate the speed of each device. A typical example of how useful cache is - Intel has produced a range of processors called Celeron - these generally have 16kb of Cache memory and are noticeably slower than the same GHZ processor in the Pentium 4 Range which has 256kb cache. Cache is good stuff
High-speed, low-access time memory placed between a CPU and main memory in order to enhance performance. See also level-one (L1) cache and level-two (L2) cache.
Generally a small chunk of fast memory that sits between either 1) a smaller, faster chunk of memory and a bigger, slower chunk of memory, or 2) a processor and a bigger, slower chunk of memory. This is to provide a bridge from something that's comparatively very fast to something that's comparatively slow. Most computers have cache memory that holds some of the information from main memory. When the processor needs the information it takes it from the speedy cache instead of the slower main memory. Cache memory GREATLY increases the speed of a computer by storing data that is most often accessed.
A small high speed memory device designed to supply the processor with the most frequently requested instructions and data. Also known as cache Random Access Memory (RAM). Cache memory can be three to five times faster than traditional system memory. Level 1 (L1) cache refers to the processor's built-in cache memory, while level 2 (L2) cache refers to the cache memory on the motherboard external to the processor.
Very fast local storage memory that the processor uses to improve average memory response time. To maintain full speed, the CPU must have instructions and data in an on-chip cache memory, thus avoiding any need to go off-chip to access external memory. Level one (L1) cache is the highest speed memory in a system and today is most often available on the CPU device. Some CPUs do not have an on-board cache. In this case, the L1 cache is fast external (and expensive) SRAM tightly coupled to the CPU, with the capability of operating at near-CPU speeds.
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.
A fast, random-access system for storing frequently accessed data in RAM
A small, high-speed, memory (usually SRAM) used to buffer the central processing unit from any slower, lower cost memory devices such as DRAM. The high-speed cache memory is used to store active data( ), while the bulk of the data resides in the slower memory.
High-speed memory closely attached to a CPU, containing a copy of the most recently used memory data. When the CPU's request for instructions or data can be satisfied from the cache, the CPU can run at full rated speed. In a multiprocessor or when DMA is allowed, a bus-watching cache is needed.
Fast semiconductor memory, which when used with a slower but larger capacity array, can provide significant performance benefits when retrieving data recently used rather than waiting for the large array to find it.
Cache memory is a small chunk of fast memory that greatly increases the speed of a computer by storing data that is most often accessed.
(Memoire Cache) : Very fast memory (generally SRAM) used often as intermediate between the CPU and the central storage, thus accelerating the system throughput. For example, on a 100MHz CPU, one cycle is executed in 10 ns, that is much faster than the 70 ns RAM cycle.
A small amount (normally less than 1MB) of high-speed memory residing on or close to the CPU. Cache memory supplies the processor with the most frequently requested data and instructions. Level 1 cache (primary cache) is the cache closest to the processor. Level 2 cache (secondary cache) is the cache second closest to the processor and is usually on the motherboard.
Cache RAM is high-speed memory (usually SRAM) which is dedicated to storing frequently requested data. If the CPU needs data, it will check in the high-speed cache memory first before looking in the slower main memory. Cache memory may be three to five times faster than system DRAM. Most computers have two separate memory caches; L1 cache, located on the CPU, and L2 cache, located between the CPU and DRAM. L1 cache is faster than L2, and is the first place the CPU looks for its data. If data is not found in L1 cache, the search continues with L2 cache, and then on to DRAM.
Pronounced "cash memory." A relatively small section of very fast memory (often static RAM) reserved for the temporary storage of the data or instructions likely to be needed next by the processor. ... more
