()ouble ()ata ()ate-Synchronous DRAM, a type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip's data throughput. DDR-SDRAM consumes less power and is also called SDRAM II.
Day Delegate Rate. A rate charged by a venue for usage of conference facilities. It often will include room hire, 2-3 servings of tea / coffee / biscuits, OHP and screen, flipchart, pens and paper and water.
Double Data Rate memory. Memory chips that are double the speed of standard SDRAM memories. DDR also consumes less power, which makes it well-suited to notebook computers. The various numbers, DDR266/333/400, represent the bus speed of the memories.
( ouble ata ate) is a technology designed to double the clock speed of the memory. It activates output on both the rising and falling edge of the system clock rather than on just the rising edge, potentially doubling output.
Double Data Rate. A type of SDRAM (as defined below) that delivers data at double the rate for a given clock frequency. The bandwidth in a PC of DDR PC266 parts with 64-bit bus using a 133MHz clock is over 2 GBytes/second.
Double Data Rate Synchronous Dynamic RAM (DDR SDRAM) can improve memory clock speed. Sometimes doubling output, it activates output on both the rising and falling edge of the system clock rather than on just the rising edge.
(Double Data Rate) or DDR SDRAM The next generation of the current SDRAM. DDR finds its foundations on the same design core of SDRAM, yet adds advances to enhance its speed capabilities. As a result, DDR allows data to be read on both the rising and the falling edge of the clock, delivering twice the bandwidth of standard SDRAMS. DDR essentially doubles the memory speed from SDRAMs without increasing the clock frequency
Draw-down ratio - As the heated polymer exits the die, it exits at a specific thickness, as defined by the die gap. It is then drawn down to a thinner gauge, based on the speed of the take-off equipment. This is known as draw down.
