Double Data Rate SDRAM

Typical DDR SDRAM clock rates are 133, 166 and 200 MHz (7.5, 6, and 5 ns/cycle).
While the access latency of DRAM is fundamentally limited by the DRAM array,  has very high potential bandwidth.
the supply voltage was reduced from 3.3 to 2.5 V. DDR SDRAM is not backwards compatible with SDR SDRAM.
