An arithmetic logic unit (ALU) cell, having a narrow pitch for straightforward cascading and integration with a memory array or similar device, also able to efficiently perform AND, NAND, OR, NOR, XOR, XNOR, INVERT, SET and CLEAR operations, and ripple carry addition. The ALU has particular utility in a multiport random access memory (RAM) based multiprocessor.
