MEMORY DEVICE ARCHITECTURE USING MULTIPLE CELLS PER BIT

Abstract:

Embodiments relate to an architecture that allows for less precision of demarcation read voltages by combining two physical memory cells into a single logical bit. Reciprocal binary values may be written into the two memory cells that make up a memory pair. When activated using bias circuitry and address decoders the memory cell pair creates current paths having currents that may be compared to detect a differential signal. Embodiments are directed to writing and reading memory cell pairs.
