Abstract:
A memory includes a memory cell, one bitline coupled to the memory cell, a sense amplifier coupled to the one bitline, a timing circuit configured to enable the sense amplifier during a read operation, a control circuit configured to enable the sense amplifier independent of the timing circuit, and a pull-up circuit configured to pull up the one bitline while the sense amplifier is enabled by the control circuit. The method includes enabling a sense amplifier in a read operation by a timing circuit. The sense amplifier is coupled to at least one bitline, and the at least one bitline is coupled to a memory cell. The method further includes enabling the sense amplifier independent of the timing circuit in a second operation and pulling up the at least one bitline by a pull-up circuit while the sense amplifier is enabled in the second operation.
