Abstract
A semiconductor storage device includes an external input/output port. A system bus of a server, which is extended to outside of the server, is connected to the external input/output port directly as a serial interface.
Claims16
A semiconductor storage device comprising:
- an external input/output port to which a system bus of a server, which is extended to outside of the server, is connected directly as a serial interface.
A semiconductor storage device comprising:
- an external input/output port to which a system bus of a server, which is extended to outside of the server, is connected directly as a serial interface;
- and
- a device controller that connects to the server using predetermined number of links among serial transmission links of the serial interface, which are successful in connection on initialization.
A semiconductor storage device comprising:
- an external input/output port to which a system bus of a server, which is extended to outside of the server, is connected directly as a serial interface;
- and
- a device controller that connects to the server using predetermined number of links among serial transmission links of the serial interface, which are successful in connection on initialization, wherein:
- the device controller comprises:
- an external link detection section that detects the serial transmission links, which are successful in connection;
- and
- a first register that stores a detection result of the external link detection section, the first register that can be accessed from an outside of the device.
