Abstract:
1. A method of developing a design of a non volatile memory comprising: exposing a non volatile memory made according to a first design to particle radiation of a species having an atomic mass of 50 or greater for sufficient time and of sufficient energy to emulate memory cell dielectric damage due to read/write cycles of a plurality of the non volatile memory cells of the non volatile memory and for the species to pass through the non volatile memory to emulate memory cell dielectric damage due to program/erase cycles of a plurality of non volatile memory cells of the non volatile memory; performing tests on the non volatile memory made according to the first design after the exposing to generate results of the tests; and determining a reliability specification of the non volatile memory made according to the first design using the results of the tests, wherein the reliability specification is based on at least 100,000 program/erase cycles.
