Abstract

An improved non-volatile memory array comprises a plurality of memory cells, at least one of the memory cells comprising a three-terminal non-volatile storage element for storing a logical state of the at least one memory cell. The memory array further comprises a plurality of write lines operatively coupled to the memory cells for selectively writing the logical state of one or more memory cells in the memory array, and a plurality of bit lines and word lines operatively coupled to the memory cells for selectively reading and writing the logical state of one or more memory cells in the memory array. The memory array is advantageously configured so as to eliminate the need for a pass gate being operatively coupled to a corresponding non-volatile storage element in the at least one memory cell.
