Abstract
Methods and apparatus are disclosed, such as those involving a flash memory device. One such method includes storing data on memory cells on a memory block including a plurality of word lines and a plurality of memory cells on the word lines. The word lines comprising one or more bottom edge word lines, one or more top edge word lines, and intermediate word lines between the bottom and top edge word lines. The data is stored first on memory cells on the intermediate word lines. Then, a remaining portion, if any, of the data is stored on memory cells on the bottom edge word lines and/or the top edge word lines. This method enhances the life of the flash memory by preventing a premature failure of memory cells on the bottom or top edge word lines, which can be more prone to failure.
