Energy Efficient Writing Techniques for Non-volatile Resistive Crossbar Arrays with Selectors (ENERGY EFFICIENT WRITE SCHEME FOR NON-VOLATILE RESISTIVE CROSSBAR ARRAYS WITH SELECTORS)

摘要

A method of adaptively and dynamically setting a bias technique of a crossbar array for a write operation includes: performing a read before write operation to determine the number n of cells to be written during a write operation; Comparing (n) to a predetermined threshold to determine an efficient bias technique; Setting at least one voltage regulator to provide a bias voltage according to an efficient bias technique; And performing a write operation. An energy efficient crossbar array device and a method of determining a threshold for determining an efficient biasing technique of a crossbar array are also described.
