What is an SRAM soft error?


A soft error is a bit upset error. The device is not damaged permanently and will operate properly after data is rewritten. A soft error occurs when an alpha-particle or neutron hits the Si substrate, and the number of electrons absorbed to a memory cell exceeds the critical charge. The soft error rate increases as finer process is adopted, because it becomes more difficult to keep stored charge for data storage.
