ABSTRACT:
A voltage generator is provided in a DRAM to generate the appropriate voltage for programming antifuses. In one embodiment of the present invention, a high voltage charge pump is provided on a DRAM product to generate the high voltage necessary for programming antifuses. In one embodiment, the high voltage charge pump includes a plurality of transistors in series to produce a programming voltage that is some multiple of the supply voltage to the memory less.
