Abstract

PURPOSE:To realize the rewritable programmable logic array constituted with rewritable memory cell groups located at the cross points of row and column lines and connected on the both lines. CONSTITUTION:On the cross points of the row and column lines, the memory cell group 12 of current switching type are located. When write-in is made on the cross points on the row lines W2<(1)>, the write-in pattern 11011111 is given from the decoder circuit 114 to the row line 112. This logic pattern is the address designating the row line W2<(1)> in the array. Next, the pattern to be written in is stored in the write-in and readout circuit 14 to write in to the address given with the activation of the decoder circuit 114. At readout, the row line 112 is activated via the decode circuit 111 and it is performed by taking logic 0 for one row line.
