Abstract
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.
