<P>PROBLEM TO BE SOLVED: To provide a memory mounting an internal power circuit, which achieves stable supply of an internal power while suppressing increase in power consumption by reducing a circuit area when an internal power is generated based on an external power and supplied to the memory. <P>SOLUTION: In a region in which an external power 102 is at a normal voltage, an internal power 103 is generated by only using an internal voltage depression power block 101. And in a region in which the external power 102 is at a low voltage, the internal power 103 is generated by using an internal voltage rising power block 112 in addition to the internal voltage depression power block 101. <P>COPYRIGHT: (C)2013,JPO&INPIT |
