SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

PURPOSE:To decrease current consumption by forming an AND or an NAND gate array part of a programmable logic array with an MOSFET. CONSTITUTION:The programmable logic array consists of an AND gate array 100 and an NOR gate array 200 and a feedback circuit 300 is arranged as required. The array 100 consists of MOSFETs and performs only the AND operation on plural logical inputs X1-Xm inputted externally. The array 200 consists of bipolar transistors and performs the OR operation on plural logical outputs Y1-Yn outputted from the array 100. Thus, logical outputs P1-Pj are obtained from the array 200.
