Fast Low Power 4 Transistor 4 Memristor Sense Amplifier

Abstract

With the continuous improvement of performance such as speed, power consumption and area of microprocessors and System on Chip (SoC), transistor response speed and chip integration aggravate the fluctuation of transistor threshold voltage, which brings about the improvement of memory performance. Great challenge. Memristors improve the overall performance of integrated circuits due to the advantages of non-volatility, high speed and infinite endurance, and compatibility with CMOS integrated circuit technology. The delay time of the circuit is 20ps, the total circuit current is 124$\mu$A, the circuit power consumption is 2.976 fJ, and the output state reaches full swing. In this paper, a 4T4M sense amplifier is designed to improve the function of the sense amplifier circuit.
