Abstract
We present a soft-error immune 12T SRAM cell for space applications, namely we-Quatro, and design a 4KB radiation-hardened macro of this SRAM in 28nm FD-SOI. Previously, 10T Quatro has been considered promising for this purpose, however suffers from extremely poor writability under parametric variations. Despite of two more transistors, we-Quatro delivers the same cell area as Quatro. Our simulations and measurements show that our 4KB macro provides robust read and write stabilities for wide supply voltage range of 0.6∼1V. More critically, the measured soft-error resilience of we-Quatro is comparable to that of Quatro, significantly better than that of 6T SRAM.
