Description

ABSTRACT:
The present invention is directed to a logic circuit for controlling the read latency time of a memory circuit. The logic circuit includes a first circuit for producing a plurality of values derived from a read enable signal. Each of the values represents the read enable signal delayed by a predetermined period of time. The logic circuit also includes a second circuit for selecting one of the plurality of values in response to at least one control signal. The selected value enables a read operation of the memory circuit. A method for controlling the read latency time of a memory circuit is also presented.
