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