Double Data Rate SDRAM. Formerly termed ìSDRAM II.î See previous section for a detailed discussion.
double-data-rate SDRAM — A type of SDRAM that doubles the data burst cycle, improving system performance.
(Double Data Rate Synchronous Dynamic Random-Access Memory) The latest generation of SDRAM technology. Data is read on both the rising and the falling edge of the computer clock, thereby delivering twice the bandwidth of standard SDRAM. With DDR SDRAM, memory speed doubles without increasing the clock frequency.
Double Data Rate SDRAM refers to a type of synchronous DRAM memory, which can transfer data on both the rising and falling edge of the clock cycle, rather than just on the rising edge as with single data rate SDRAM. This results in twice as much data throughput. DDR SDRAM is gaining popularity in 2001 as more and more motherboards offer support for it.
Memory technology used on DIMMs that runs at twice the speed of the system clock.
DDR SDRAM or double-data-rate synchronous dynamic random access memory is a type of memory integrated circuit used in computers. It achieves greater bandwidth than the preceding single-data-rate SDRAM by transferring data on both the rising and falling edges of the clock signal (double pumped). This effectively nearly doubles the transfer rate without increasing the frequency of the front side bus.
