Abstract
A circuit is usable to generate a sense amplifier enable (SAE) signal for a static random access memory (SRAM) circuit. The circuit includes a first tracking bit line, a second tracking bit line, a tracking cell, and a control logic circuit. The second tracking bit line is electrically connected to the first tracking bit line. The tracking cell has a driving terminal and a non-driving terminal, where the non-driving terminal is connected to the second tracking bit line, and the driving terminal is connected to the first tracking bit line and configured to selectively charge or discharge a voltage on the first tracking bit line in response to a control signal. The control logic circuit is coupled to the first tracking bit line and configured to generate the SAE signal in response to the voltage level on the first tracking bit line.
