In nitride storage flash memories, the high-V-T state retention loss induced by field and temperature acceleration is compared between single cells and products. Our result reveals that the charge loss path is the same no matter which accelerating methods is used. The traps created at the bottom oxide during P/E cycling provide such leak paths. In addition, the annealing of interface states would play a role in the V-T loss during high-temperature bake.
