A recent model provides risk estimates for the deprogramming of initially programmed floating gates via prompt charge loss produced by an ionizing radiation environment. The environment can be a mixture of electrons, protons, and heavy ions. The model requires several input parameters. This paper extends the model to include TID effects in the control circuitry by including one additional parameter...
A recent model provides risk estimates for the deprogramming, of initially programmed floating gates, via prompt charge loss produced by an ionizing radiation environment. The environment can be a mixture of electrons, protons, and heavy ions. The model requires several input parameters. Parameters intended to produce conservative risk estimates for the Samsung 8 Gb SLC NAND flash memory are given,...
Heavy ion, proton and electron single-event effect measurements of 8Gb Samsung single level NAND flash memory are reported. An increase in the heavy ion single bit upset (SBU) cross section was observed on devices that were irradiated with 60Co previously. The proton susceptibility is less than expected. No electron induced upsets were observed.
SEE measurements and TID response for 25-32 nm Micron Technology NAND flash memories are reported. Radiation results of SLC parts are compared with results from MLC and TLC parts. The TLC device showed a very poor response to TID at low dose levels.
