<P>PROBLEM TO BE SOLVED: To prevent a malfunction of a system caused by a peak current of a flash memory. <P>SOLUTION: A mode change-over control circuit 23 has a function of changing over a high-speed operation mode in which a peak consumption current in the flash memory becomes a 1st value to/from a low consumption current mode in which the current becomes a 2nd value lower than the 1st value. When the flash memory is applied to a system to be easily influenced by a peak current and a page size of the flash memory is large, the flash memory is made to operate in the low consumption current mode. In other cases, the flash memory is made to operate in the high-speed operation mode. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
