Abstract

A system and method for automatically adjusting one or more electrical parameters in a memory device, e.g., SRAM arrays. The system and method implements an SRAM sensing sub-array for accelerated collection of fail rate data for use in determining the operating point for optimum tradeoff between single event upset immunity and performance of a primary SRAM array. The accelerated fail rate data is input to an algorithm implemented for setting the SEU sensitivity of a primary SRAM memory array to a predetermined fail rate in an ionizing particle environment. The predetermined fail rate is maintained on a real-time basis in order to provide immunity to SEU consistent with optimum performance.
