Abstract
A method for screening memory cells includes erasing the memory cells, weakly programming the memory cells to a modified erased state, performing a first read operation on the memory cells after the erasing and the weakly programming, screening any of the memory cells that exhibit a read current during the first read operation below a margin read current threshold M, baking the memory cells after the first read operation, performing a second read operation on the memory cells after the baking, and screening any of the memory cells that exhibit a read current during the second read operation below the margin read current threshold M
