A method and flash memory device employing the method includes a flash memory device having a logic routine saved on the flash memory being a computer readable medium. The flash memory device generates a plurality of memory inputs and outputs. The logic routine determines a memory input and/or memory output operation, and incrementally counts memory inputs and memory outputs using a counter function of the logic routine. The logic routine determines the total number of the plurality of memory inputs and outputs using the counter function. Additionally, the logic routine generates an alert signal when the total number of the memory inputs and outputs exceeds a predetermined value programmed in the logic routine.
