ABSTRACT:
A programmable logic device is disclosed which includes sense amplifiers for determining the programmed/unprogrammed state of product terms coupled to respective ones of the sense amplifiers. A control circuit is provided for the sense amplifiers to permit, under control from a control signal, disabling sense amplifiers which are not being used in the achievement of the logical function of the programmable logic device to avoid unnecessary use of current by the sense amplifiers which are not operative for the function being implemented. In addition to eliminating current drain by the unused sense amplifier, the control circuit also ensures that a low output signal will always be provided at the output of the disabled sense amplifier to avoid potentially indicating an incorrect logical output from the sense amplifier which is connected to other devices in the programmable logic device.
