Abstract
A method of erasing memory cells of a memory device includes programming memory cells if the erasing procedure is suspended. The erasing procedure can include pre-programming, erasing, and soft-programming of memory cells in a selected memory unit. If a suspend command is received, for example to allow for a read operation of memory cells of another unit of memory, the erasing procedure stops the pre-programming, erasing, or soft-programming, and proceeds with programming one or more memory cells of the memory unit that was being erased.
