Mitigation technique against multi-bit-upset without area, performance and power overhead

Abstract

In this work, we propose a technique for mitigating multi-bit-upset (MBU) which cannot be corrected by Error-Correction-Code (ECC) with using bit-line alternation and narrow deep-N-well. This technique mitigates MBU without area, performance and power overhead. The mitigation efficiency is evaluated with alpha and neutron acceleration experiments. The experimental results show excellent mitigation efficiency of the proposed technique.
