High voltage switch circuitry

摘要

The present invention relates to a high voltage switch used with a one-time programmable memory device and a method of setting a state of a one-time programmable memory device using such a high voltage switch. The memory device includes a plurality of one time programmable memory cells arranged in an array and adapted to be programmed using a high voltage, wherein each of the memory cells includes at least one storage element and two gated fuses connected to the storage element. A high voltage switch is connected to at least one of the memory cells and is adapted to switch in a high voltage.
