Abstract:
A method for operating a sense amplifier in a one-switch one-resistance (1S1R) memory array, includes: generating a regulated full voltage and a regulated half voltage; applying the regulated full voltage and regulated half voltage to selected and unselected bit lines of the 1S1R memory array during read operations as an applied read voltage; and inducing and compensating for a sneak-path current during read operations by adjusting the applied read voltage based on the cell state of an accessed bit cell and an amplitude of the sneak-path current.
