Abstract
A method of programming a memory array is provided, including accessing a plurality of word lines of the memory array by providing a plurality of voltage steps sequentially after one another to the respective word lines, and accessing a plurality of bit lines of the memory array each time that a respective word line is accessed, to program a plurality of devices corresponding to individual word and bit lines that are simultaneously accessed, each device being programmed by breaking a dielectric layer of the device, accessing of the bit lines being sequenced such that only a single one of the devices is programmed at a time.
