Design of SEU-hardened CMOS memory cells: the HIT cell

Abstract

A memory cell, called HIT cell (heavy ion tolerant cell), designed to be SEU-immune is presented. Compared to previously reported design hardened solutions, the HIT cell is less SEU-sensitive, features better electrical performances and consumes less silicon area.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
