A low power and high reliability magnetic full adder based on separated pre-charge sensingamplifier

Abstract

Magnetic tunnel junction (MTJ) entrenched in complementary metal-oxide-semiconductor to built the Nonvolatile memory and logic circuits. Nevertheless this type of circuit suffers from low reliability in sensing operation and memory unit. This leads to limitation of its practical application for logic computation. This paper presents a new design of magnetic full adder to overcome this issue by separated pre-charge sensing amplifier circuit. The proposed method can operate at a lower supply voltage less than one volt by separating the discharging and evaluation stages of the sensing operation. The higher sensing reliability is achieved by reducing the effect of process variation. When compared to previous proposed method it preserves high speed and low power consumption. In this paper all the circuits are designed by post layout simulation tool.
