Memory interface architecture for maximizing access timing margin

An apparatus comprising a control circuit, a buffer circuit and a memory. The control circuit may be configured to present a plurality of pairs of signals in response to (i) one or more input signals operating at a first data rate and (ii) an input clock signal operating at a second data rate. The second signal in each of the pairs comprises a clock signal operating at the second data rate. The buffer circuit may be configured to generate a buffered signal in response to each of the pairs of signals. Each of the buffered signals operates at the second data rate. The memory may be configured to read and write data at the second data rate in response to the buffered signals.
