The SEU Cross Section Estimation in SRAM Induced by Protons of Space Environment

Xunying Zhang, Shen Xu-bang

Open publisher page 7 citations

Abstract

The main goal of this paper is to propose an approach to calculate proton induced SEU cross sections. The starting point is the RPP sensitive volume model and some reasonable assumptions. An approximate analytic calculational model is presented, by which the valid number of the heavy ions induced by the interaction of proton and Si nuclei will be obtained. Then, the saturated proton SEU cross section for the typical 6T SRAM can be calculated by using this number and the experimental data of heavy ions. The calculated proton SEU cross section is in good agreement with experiment results.
