Abstract
A synchronous data processing system includes a memory module to store data and a memory controller coupled to the memory module. The memory controller includes a clock inverter to receive an input clock signal and to transmit an inverted clock signal to the memory module. The inverted clock signal incurs a first propagation delay prior to reaching the memory module as a memory clock signal. A write data buffer is coupled to the memory module. The write data buffer transmits data to the memory module in response to the input clock signal. An asynchronous first-in-first-out (ASYNC FIFO) buffer is coupled to the memory module. The ASYNC FIFO buffer reads data from the memory module in response to a feedback signal generated by feeding back the memory clock signal to the ASYNC FIFO buffer.
