Title
Multiple-Cell-Upset Tolerant 6t Sram Using Nmos-Centered Cell Layout
Abstract
This paper presents a proposed NMOS-centered 6T SRAM cell layout that reduces a neutron-induced multiple-cell-upset (MCU) SER on a same wordline. We implemented an 1-Mb SRAM macro in a 65-nm CMOS process and irradiated neutrons as a neutron-accelerated test to evaluate the MCU SER. The proposed 6T SRAM macro improves the horizontal MCU SER by 67-98% compared with a general macro that has PMOS-centered 6T SRAM cells.
