Abstract
An apparatus for improving stability of a magnetoresistive random access memory over process and operational variations includes a current reference circuit that provides a reference current control signal to variable analog control circuitry. The variable analog control circuitry is connected to receive control signals from the current reference. The variable analog control circuitry generates a word current reference signal in response to the reference current control signal and further generates a source current reference signal in response to the reference current control signal. At least one word current source is connected to receive the word current reference signal. At least one sense current source is connected to receive the source current reference signal.
