Flash memory inherently has a limited number of write/erase cycles. Inevitably, electrons get trapped where they’re not wanted, and the voltage levels shift, eventually causing read or write failure. Any given bit of flash memory is specified for a certain number of cycles before failure, but really it’s a random process and there could be a problem long before the numbers would predict on average.
