2. DDR2 SDRAM - Wikipedia

   en.wikipedia.org/wiki/DDR2_SDRAM

   DDR2 SDRAM was designed with such a scheme to avoid an excessive increase in power consumption. DDR2's bus frequency is boosted by electrical interface improvements, on-die termination, prefetch buffers and off-chip drivers. However, latency is greatly increased as a trade-off. The DDR2 prefetch buffer is four bits deep, whereas it is two bits ...

   Memory controller with differential serial connections to DDR2 FB-DIMMs. The AMB is visible in the center of each DIMM. A Fully Buffered DIMM (FB-DIMM) is a type of memory module used in computer systems. It is designed to improve memory performance and capacity by allowing multiple memory modules to be each connected to the memory controller ...

   Corresponding 240-pin DIMMs are known as PC2-3200 through PC2-6400. DDR2 SDRAM is now available at a clock rate of 533 MHz generally described as DDR2-1066 and the corresponding DIMMs are known as PC2-8500 (also named PC2-8600 depending on the manufacturer). Performance up to DDR2-1250 (PC2-10000) is available.

7. DDR SDRAM - Wikipedia

   en.wikipedia.org/wiki/DDR_SDRAM

   DDR2 started to be effective by the end of 2004, as modules with lower latencies became available. [ 19 ] Memory manufacturers stated that it was impractical to mass produce DDR1 memory with effective transfer rates in excess of 400 MHz (i.e. 400 MT/s and 200 MHz external clock) due to internal speed limitations.
