<p><P>PROBLEM TO BE SOLVED: To provide a low voltage detector which can detect accurate low voltage since it is not affected by change in the temperature, process, and operation voltage. <P>SOLUTION: The detector comprises a first flash memory cell driven by a ground voltage for maintaining the potential of a first node to a prescribed potential, a second flash memory cell driven by a power source voltage for controlling the potential of a second node, and a comparator for comparing the potential of the first node with the potential of the second node. <P>COPYRIGHT: (C)2003,JPO</p> |
