Abstract
Disclosed is an apparatus for and a method of overcoming signal delay problems in a read-out path occurring in connection with pipelined memory circuits. A latch type sense amplifier (SA) is used to receive the memory cell logic levels during a pre-charge state in a cycle prior to read-out. Thus, the SA may quickly provide an output signal during a read latch clock cycle. The SA output is passed through a dynamically enabled logic circuit to a latch circuit for holding the receiving logic value for use in the next clock cycle.
