ABSTRACT:
The present invention provides a configurable sense amplifier for a programmable logic device (PLD) that can be turned on or off as needed. Specifically, a latch stores an enable or disable state which respectively connects or disconnects the sense amplifier to a voltage source Vcc. In this manner, the sense amplifier remains on or off until the latch is reset. In one embodiment of the present invention, a reset circuit provides a predetermined value to the latch and a pass transistor to prevent floating during a power-on operation.
