A novel radiation tolerant SRAM design based on synergetic functional component separation for nanoscale CMOS

Abstract

This paper presents a novel SRAM design for nanoscale CMOS. The new design addresses the problem of low radiation tolerance and high instability for SRAM memories at feature size of 32nm. The novelty of our approach originates from the synergetic functional component separation, where each component serves its unique operational function and has minimal effect on performance of others. The design consists of three different components: the first component is used to store the data, the second one is designed to protect the data at the most vulnerable state and last component serves to extract the data from the SRAM cell. We performed comparative analysis of our design against conventional radiation-tolerant designs in terms of power consumption, level of radiation tolerance, performance, area and stability. The benefits of our new design (high radiation tolerance, high stability, fast performance) were confirmed by extensive simulations in different 32nm technology environments (low power, high performance, bulk).
