Internet的爆炸式增长已经极大地加速了对高速数据通信系统的需求，这就要求快速的处理器及和外围设备的高速接口。
The explosive growth of the Internet has increased the demand for highspeed
data communications systems that require fast processors and
high-speed interfaces to peripheral components. While the processors in
these systems have improved in performance, SRAM performance has
not kept pace. New SRAM architectures are evolving to support the highthroughput
requirements of current systems. One such architecture is
quad data rate (QDR) SRAM, which provides more than four times the
bandwidth of other SRAM architectures.
