Single integrated circuit having both a memory array and an arithmetic and logic unit (ALU)

摘要

An arithmetic and logic unit implemented in a memory array. The memory array has a plurality of memory cells each with a memory storage element and each accessible via a word line and at least one bit line, The arithmetic and logic unit comprises a plurality of logic circuits coupled to the word and bit lines in place of the memory storage elements of certain memory cells, Each of a plurality of pull down logic circuits implements an arithmetic and/or logic function,
