Abstract
Programmable Logic Array PLA) cells are arranged at intersections of input lines and output lines of the array. Particular PLA cells to be programmed are arbitrarily selected by word line and bit line decoders. Switches for programming the PLA cells to implement a desired logic function are controlled by data stored in a random access memory whereby programming of the PLA can be changed arbitrarily and during operation of a system including the PLA.
