A re-programmable logic array is disclosed which has an AND array disposed for receiving n input signals on n rows of m cells per row, and an OR array providing k output lines on k rows of m cells per row. The AND and OR arrays are coupled together by m term lines. Each of the rows of the AND and OR arrays include shift register means of m charge storage elements having an input terminal coupled to the first of the m charge storage elements and an output terminal coupled to the mth one of the m charge storage elements. Multiplexors are coupled to each of the rows of both the AND and OR arrays to select between a programming operation and a recirculating refresh operation.

This disclosure relates to a programmable logic array having an AND array disposed for receiving n input signals, an OR array providing k output signals on k output lines and m term lines coupling the AND and OR arrays together. New and improved AND and OR arrays are disclosed wherein the AND array includes n X m cells and each cell has first and second transistor means coupled in series between one of the term lines and a reference potential. Each cell includes a storage element that has an output terminal coupled to the control element of the first transistor means and one of the n input terminals is coupled to the control element of the second transistor means. The OR array includes m X k cells wherein each cell has third and fourth transistor means coupled in series between one of said output lines and a reference potential. Each of the OR array cells also includes a storage element having an output terminal coupled to the control element of the third transistor and one of the m term lines is coupled to the control element of the fourth transistor.
