Abstract
We describe a multi level flash memory device and program method. The multi level flash memory device includes a plurality of memory cells, each storing an amount of charge indicative of more than two possible states and control circuitry coupled to the memory cells. The control circuitry to applying a programming voltage alternating with a verification voltage to the memory cells until all are at a desired state and applying at least one additional programming voltage to the cells in a highest state without applying a verification voltage. The method includes applying at least one programming pulse to the cells, verifying that each cell has reached the desired state, selecting the cells that are programmed for a highest state, and applying at least one additional programming pulse to the selected cells without further verifying their state.
