Non-uniform state spacing in multi-state memory element for low-power operation

Abstract:

A method of setting multi-state memory elements into at least one low-power state may include receiving a command to cause a memory element to transition into one of three or more states; applying a first signal to the memory element to transition the memory element into the one of the three or more states, where the three or more states are evenly spaced in a portion of an operating range of the memory element; receiving a command to cause a memory element to transition into a low-power state; applying a second signal to the memory element to transition the memory element into the low-power state, where the low-power state is outside of the portion of the operating range of the memory element by an amount greater than a space between each of the three or more states.
