DDR SDRAM

Double Data Rate (DDR) SDRAM

Micron Technology Inc.

DDR allows applications to transfer data on both the rising and falling edges of a clock signal, doubling bandwidth and vastly improving performance over SDR SDRAM. Basically, DDR gives you source-synchronous data capture at twice the clock frequency; i.e. 133 MHz equals DDR-266. To achieve this functionality, Micron uses a 2n-prefetch architecture where the internal data bus is double the size of the external data bus, so data capture can happen two times each clock cycle.
