Total dose radiation hardening and testing issues of CMOS static memories

A radiation hardened circuit should be both processed and designed for hardness. It is demonstrated that the MOSIS two micron CMOS technology exhibits radiation hardened properties, making it particularly suitable for a design methodology in which circuitry is added to compensate for the radiation induced degradation of the zero input noise margin. The non-ideal behavior of the compensation circuitry is explained and application of the circuitry in a static RAM cell is explored.<
