Description:
DDR2 SDRAM or double-data-rate two synchronous dynamic random access memory is an evolutionary improvement over its predecessor, DDR SDRAM. Its primary benefit is the ability to operate the external data bus twice as fast as DDR SDRAM. This is achieved by improved bus signaling, and by operating the memory cells at half the clock rate (one quarter of the data transfer rate), rather than at the clock rate as in the original DDR. DDR2 memory at the same clock speed as DDR will provide the same bandwidth but markedly higher latency, providing worse performance. PC2-6400 is DDR2-800 and runs at 800 MHz bus speed with a maximum transfer rate of 6400 MB/s.
