CIRCUIT AND METHOD FOR GENERATING SENSE AMP ENABLE SIGNAL FOR STATIC RAM, AND STATIC RAM COMPRISING THE SAME CIRCUIT

摘要

Disclosed are a sense AMP enable signal generating circuit for SRAM, a method thereof, and SRAM with the generating circuit. The sense AMP enable signal generating circuit of the present invention uses one or more cell columns selected from a cell array of the SRAM as a tracking cell column, thereby not requiring a separate replication or dummy word line. When a read operation is started as one among word lines is operated in a logic high state, the sense AMP enable signal generating circuit of the present invention generates a tracking signal (TRKBL) by tracking a voltage change in a bit line of the tracking cell column, and generates a sense AMP enable signal by using the TRKBL.
