Abstract
A method of operating magneto-resistive random access memory (MRAM) cells includes providing an MRAM cell, which includes a magnetic tunneling junction (MTJ) device; and a selector comprising a source-drain path serially coupled to the MTJ device. The method further includes applying an overdrive voltage to a gate of the selector to turn on the selector.
