A semiconductor memory device includes, in addition to a first switching circuit with which a data system signal line between a plurality of semiconductor memory portions and a memory controller is branched, a second switching circuit with which a non-data system signal line between the plurality of semiconductor memory portions and the memory controller is branched, and the first and second switching circuits share a switching signal line.

Semiconductor memory device, storage system, and computer

Provided is a storage subsystem capable of maintaining the reliability of I/O processing to a host apparatus, even if there is an unauthorized access from a processor core to a switch circuit, by applying a multi-core system to a processor. A multi-core processor is applied to a second logical address space that is different from a first logical address space to be commonly applied to multiple controlled units such as a host interface to be accessed by the processor. The switch circuit determines the processor core that issued an access based on an address belonging to a second address space, and maps an address containing in an access from the processor core to an address of a first address space.

Storage subsystem and its control method

An electropressing apparatus includes an electric motor driven through a motor driver circuit to operate a pressing ram through a rotational mechanism constructed to move the pressing ram in a vertical direction relative the workpiece. Various detecting and control arrangements are used to detect, memorize, set and change the following: an initial position of the pressing ram; an upper limit stop position of the pressing ram with respect to the workpiece; a lower limit stop position of the pressing ram immediately above the workpiece; a position at which the pressing ram starts to apply a pressure to the workpiece; and a terminal position at which the pressing ram stops to apply pressure to the workpiece.
