Classification: CPC G  H | IPC G  H

Claim 0:
1. A semiconductor device with contact check circuitry, comprising:
a plurality of pads including a first pad and a second pad;
a voltage detection circuit, coupled to the first pad and the second pad, for generating at least one voltage detection signal;
wherein the at least one voltage detection signal includes a first voltage detection signal and a second voltage detection signal, and the voltage detection circuit comprises:

a first voltage divider, coupled between the first pad and a first power supply terminal, for generating the first voltage detection signal; and
a second voltage divider, coupled between a second power supply terminal and the second pad, for generating the second voltage detection signal;
an internal circuit coupled to the plurality of pads; and
a contact check circuit, at least coupled to the first pad and the second pad, for comparing a first test signal received from the first pad and at least one reference signal and comparing a second test signal received from the second pad and at least one reference signal and then generating a check result signal according to these comparisons.
