摘要： PURPOSE:To provide a power controller which cuts off the power supplied to an external device control circuit included in an LSI circuit when no processing request is given to the LSI circuit and therefore no supply of power is needed to the LSI circuit and thus can reduce the power consumed by an information processor. CONSTITUTION:When a processing request is completed to an input/output device control circuit 104 via an interface circuit 101, the circuit 101 reports this fact to a power control means 102 by a ready signal (c). Then the means 102 asks a power switching means 103 to stop the supply of power via a switch signal (e) as long as no processing request is received for a fixed time. Thus the supply of power is stopped to the circuit 104.

摘要： PURPOSE:To prevent excess writing to a successful flash memory by performing a rewriting processing for only a flash memory in failure at the time of the writing processing for a memory system which uses plural flash memories. CONSTITUTION:The flash memory system is provided with an information holding circuit 112 which holds a diagnostic result showing whether or not writing is successful and further provided with a writing inhibiting circuit 113 which inhibits data from being written in successful flash memories 105 and 106 on the basis of the diagnostic result held in the information holding circuit 112. Consequently, overwriting to the flash memories which are successful in writing can be prevented, so the electric power that the flash memories consume is reducible.

摘要： PROBLEM TO BE SOLVED: To boost the information processing unit in a state before rewrite when the information processing unit is restarted even when a power failure or the like takes place during rewrite of an operating system in a flash memory. SOLUTION: A CPU 108 copies an operating system stored in a flash memory 106 to an idle area of a flash memory 105. The copying of the operating system is stored in a storage circuit 104 and an information storage circuit 1012 backed up by a battery. While the information of representing the copying as above is stored in the information storage circuit 1012, an access conversion circuit 1011 of a bridge circuit 101 converts a read request stored in the flash memory 106 of the CPU 108 into a read request of the operating system copied in the flash memory 105. The CPU 108 rewrites the operating system stored in the flash memory 106, based on rewrite information of the operating system read out of an FDD 103.
