Title: Single-event upset rate estimates for a 16-K CMOS (complementary metal oxide semiconductor) SRAM (static random access memory). Technical report

Technical Report ·
OSTI ID:6856630

A radiation-hardened 16K CMOS SRAM was developed for satellite and deep space applications. The RAM memory cell was modeled to predict the critical charge, necessary for single-particle upset, and a function of temperature, total dose, and hardening feedback resistance. Laboratory measurements of the single-event cross section and effective funnel length were made using the Lawrence Berkeley Laboratory's 88-inch cyclotron to generate high energy krypton ions. The combination of modeled and measured parameters permitted estimation of the upset rate for the RAM cell, and the mean-time-to-failure for a 512-K word, 22-bit memory system employing error detection and correction circuits while functioning in the Adam's 90% worst-case cosmic ray environment. This report is presented in the form of a worst tutorial review, summarizing the results of substantial research efforts within the single event community.
