ABSTRACT:
A programmable logic device includes wordlines each having two sides for connection, bitlines substantially intersecting with the wordlines constituting an AND array portion in conjunction with the wordlines and a plurality of nonvolatile memory elements. Each nonvolatile memory element has data memorized therein and is connected to one of the wordlines and one of the bitlines. And the device has an OR array portion which conducts a predetermined calculation on the basis of the data read from the memory element, an input buffer circuit connected to one side of the wordlines and a decoder connected to the other side of the wordlines through a wordline driver.
