Abstract

A de-coupled memory access system including a memory access control circuit is configured to generate first and second independent, de-coupled time references. The memory access control circuit includes a read initiate circuit responsive to the first time reference and a read signal for generating a read enable signal, and a write initiate circuit responsive to the second time reference and a write signal for generating a write enable signal independent of the read enable signal for providing independent, de-coupled write access to a memory array.
