A zero-power sense amplifier for implementing a wide or multiple input NOR gate for receiving a product term of a group of array cells in a programmable logic device (PLD). In a sleep mode, or low power mode, the zero-power sense amplifier latches its previous state while drawing negligible power rather than returning to one particular state, such as a low state, as in previous devices, enabling recovery time to be reduced after entering an awake mode. The zero power sense amplifier further reduces recovery time upon powering up from a sleep mode by maintaining the product term voltage close to a threshold input voltage during sleep mode while still drawing negligible power.
