摘要:
Disclosed herein is a storage device including: a communication execution unit configured to be capable of controlling an operation state between a communication-enabled state in which data communication is possible and a pause state in which data communication is impossible; a buffer configured to store data transmitted and received by the communication execution unit; a memory configured to be capable of storing data; a memory controller configured to carry out data input and output between the memory and the buffer; and a communication controller configured to make the communication execution unit operate if data communication is carried out, and make the communication execution unit take a pause if data communication is not carried out. The communication controller switches the operation state of the communication execution unit between the communication-enabled state and the pause state in data communication depending on a data processing state of the buffer.

A card-type peripheral device having a plurality of specifications of external interfaces includes a connector configured to connect the card-type peripheral device to a connectable device connectable to the card-type peripheral device, the connector including a dedicated terminal in which an interface to be used is set; an electronic component configured to be accessed via the set interface; a plurality of interface function units each configured to control an interface compliant with one of the plurality of specifications; and a communication function unit configured to perform communication with the electronic component using one of the interface function units having a specification corresponding to a setting of the dedicated terminal.
摘要:
A card type peripheral apparatus connected to a host apparatus for communication therewith according to a specific protocol. The card type peripheral apparatus includes a plurality of configuration registers configured to be accessible by the host apparatus and to be set with diverse set information. At least one of the plurality of configuration registers is a special register configured to be set with data arbitrarily selected and fixedly established by a vendor that either fabricates or markets the card type peripheral apparatus. The special register is set with protocol identification information for discriminating the specific protocol.
