Patent ID: 8233306

Claim:
A semiconductor device comprising: a first low-voltage transistive element; a second high-voltage transistive element coupled to a first end of the first low-voltage transistive element; a burn subcircuit coupled to the first low-voltage transistive element and a latch, the burn subcircuit including a third high-voltage transistive element coupled to a fourth low-voltage transistive element, where a drain of the third high-voltage transistive element is coupled to the a second end of the first low-voltage transistive element, and a drain of the fourth low-voltage transistive element is coupled to the latch; and a fifth low-voltage transistive element coupled in parallel to the fourth low-voltage transistive element; where control logic coupled to the burn subcircuit enables a voltage divider comprising the first low-voltage transistive element, the third high-voltage transistive element, and the fifth low-voltage transistive element, in a read mode; or enables the third high-voltage transistive element and the fourth low-voltage transistive element, and burns the first low-voltage transistive element, in a program mode.
