A high voltage tolerative inverter circuit includes a first PMOS transistor with a source connected to VDDQ and drain connected to a first node; a second PMOS transistor with a source connected to the first node and a drain connected to an output; a first NMOS transistor with a source connected to VSS and a drain connected to a second node; a second NMOS transistor with a source connected to the second node and a drain connected to the output. A gate of the first PMOS transistor is controlled by a first signal having a voltage swing between VDDQ and VSS. A gate of the first NMOS transistor and the second PMOS transistor are controlled by a second signal having a voltage swing between VDD and VSS. VDD is lower than VDDQ. A gate of the second NMOS transistor is biased with a first voltage greater than VSS.

A circuit includes a fuse and a sensing and control circuit. The fuse is coupled between a MOS transistor and a current source node. The sensing and control circuit is configured to receive a programming pulse and output a modified programming signal to the gate of the MOS transistor for programming the fuse. The modified programming signal has a pulse width based on a magnitude of a current through the first fuse.

In a voltage detecting circuit, a transistor is configured as a P-type MOSFET, and includes a source connected with an input terminal, a gate connected with a ground voltage terminal and a drain connected with an output terminal. A transistor is configured as a P-type MOSFET, and includes a gate and a source connected with the output terminal and a drain connected with the ground terminal. Gate width and gate length of the transistor and gate width and gate length of the transistor are adjusted so that source-drain current flowing between the source and the drain of the transistor becomes equal to source-drain current flowing between the source and the drain of the transistor when the voltage applied to the input terminal is set to be preset trigger voltage. This configuration accomplishes detecting that the input voltage exceeds the trigger voltage with simple configuration.
