An MRAM memory integrated circuit is disclosed. Resistance, and hence logic state, is determined by discharging a first charged capacitor through an unknown cell resistive element to be sensed at a fixed voltage, and a pair of reference capacitors. The rate at which the parallel combination of capacitors discharge is between the discharge rate associated with a binary "1' and "0' value, and thus offers a reference for comparison.
