Design of Soft-Error-Aware SRAM With Multi-Node Upset Recovery for Aerospace Applications

To achieve improved speed of operation, a higher integration density and lower power dissipation, transistors are being scaled aggressively. This trend has reduced the critical charge of sensitive nodes. As a result, SRAM cells used in the high radiation environment of aerospace have become highly vulnerable to soft errors. In this paper, we propose a soft-error-aware 14T (SEA14T) SRAM cell for ae...
