Abstract
Set and reset functions are corporated in a sense amplifier such that those functions can be performed by the sense amplifier rather than by circuits connected to the sense amplifier. The set and reset functionality is added to the sense amplifier in a manner that minimally impacts the sense amplifier's performance. Accordingly, the sense amplifier includes a number of discharge paths for discharging charges that develop on its output terminals. The set and reset circuit includes a number of high conductance paths that are turned-on in response to an assertion of a set control signal or a reset control signal. When either of those control signals is asserted, the corresponding output terminal is discharged. Accordingly, the output terminals can be either set or reset, responsive to which of the control signals is asserted. When the control signals are de-asserted, the sense amplifier performs in a normal sense amplifier manner.
