Abstract:
Disclosed is a nonvolatile storage system including: a memory block having a plurality of flash memories; a flash memory power supply circuit outside of the memory block; and a flash memory controller. The flash memory power supply circuit has a plurality of types of power supply circuits for process execution, the power supply circuits for process execution generating and supplying power at a plurality of voltage levels needed to execute processes in the flash memories. The flash memory controller monitors changes of the internal states of the flash memories by communicating with the flash memories, thereby controlling the power supply circuits for process execution and the flash memories.
