DDR2 SDRAM or double-data-rate two synchronous dynamic random access memory is a random access memory technology used in electronic engineering for high speed storage of the working data of a computer or other digital electronic device.
It is a part of the SDRAM (synchronous dynamic random access memory) family of technologies, which is one of many DRAM (dynamic random access memory) implementations, and 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.
