ABSTRACT:
The present invention provides a feedback control circuit for controlling the operation of an sense amplifier circuit in accordance with the feedback of an output signal to the AND array, for a PLD having an ITD circuit. The feedback control circuit includes a storage element for storing data as to whether or not an output signal is fed back to the AND array, and a read-out circuit for reading out the data of the storage element. With the data read out from the storage element, a pulse signal output from the ITD circuit for detecting a change in the output signal is supplied to the sense amplifier circuit so as to set it in an enable state when the output signal is fed back to the AND array, and the supply of the pulse signal to the sense amplifier circuit is inhibited so as to set it in the disable state when the output signal is not fed back to the AND array.
