ABSTRACT:
A bulk voltage (VBB) level sensor for a semiconductor memory apparatus is disclosed. The VBB level detector includes a reference voltage generator for generating a first reference voltage of which level varies with temperature, a reference voltage comparator for receiving a second reference voltage and the first reference voltage to generate a third reference voltage, a bias generator for receiving the third reference voltage to generate a specific bias level, and a VBB sensor for receiving the bias level to detect VBB level.
