Abstract
A nonvolatile memory card includes memory card controllers conforming to two or more different specifications, a memory card controller changeover switch configured to enable one of the memory card controllers in response to an indication supplied from an exterior, and a nonvolatile memory that has data therein written from and data therein read to an external device under control of the enabled one of the memory card controllers.
Claims8
A nonvolatile memory card, comprising:
- memory card controllers conforming to two or more different specifications;
- a memory card controller changeover switch configured to enable one of the memory card controllers in response to an indication supplied from an exterior;
- and
- a nonvolatile memory that has data therein written from and data therein read to an external device under control of the enabled one of the memory card controllers.
A memory card adapter, comprising:
- a receptacle configured to receive a nonvolatile memory card inserted thereinto to allow data transfer between the nonvolatile memory card and a host apparatus when the memory card adapter is inserted into the host apparatus;
- and
- a memory card type changeover switch configured to select a type of the data transfer among a plurality of types of data transfers provided in the nonvolatile memory card when the nonvolatile memory card is inserted into the receptacle.
A nonvolatile memory card, comprising:
- memory card controllers conforming to two or more different specifications;
- an interface controller configured to analyze data signals performed from an exterior and to enable one of the memory card controllers in response to a result of the analysis;
- and
- a nonvolatile memory that has data therein written from and data therein read to an external device under control of the enabled one of the memory card controllers.
A nonvolatile memory card, comprising:
- memory card controllers conforming to two or more different specifications;
- a memory card controller changeover circuit configured to enable one of the memory card controllers in response to a changeover control signal;
- and
- an interface controller configured to analyze data signals performed from an exterior and to supply the changeover control signal to the memory card controller changeover circuit in response to a result of the analysis;
- and
- a nonvolatile memory that has data therein written from and data therein read to an external device under control of the enabled one of the memory card controllers.
A nonvolatile memory card, comprising:
- memory card controllers conforming to two or more different specifications;
- an interface controller configured to analyze data signals performed from an exterior and to enable one of the memory card controllers in response to a result of the analysis;
- and
- a memory card controller changeover switch configured to enable one of the memory card controllers in response to an indication supplied from an exterior;
- and
- a nonvolatile memory that has data therein written from and data therein read to an external device under control of the enabled one of the memory card controllers,
- wherein the interface controller and the memory card controller changeover switch are configured such that one of the memory card controllers is enabled in response to the result of the analysis if the result of the analysis indicates one of the memory card controllers, and is enabled in response to the indication supplied from the exterior if the result of the analysis indicates none of the memory card controllers.
A method of conducting data transfer between a host apparatus and a nonvolatile memory card when the nonvolatile memory card is inserted into a memory card adapter that is inserted into the host apparatus, said method comprising:
- causing the memory card adapter to make a setting to a switch provided in the nonvolatile memory card;
- and
- selecting one of a plurality of memory card controllers provided in the nonvolatile memory card in response to the setting of the switch.
A method of conducting data transfer between a host apparatus and a nonvolatile memory card when the nonvolatile memory card is coupled to the host apparatus, said method comprising:
- analyzing data signals performed from the host apparatus to the nonvolatile memory card;
- and
- selecting and enabling one of a plurality of memory card controllers provided in the nonvolatile memory card in response to a result of the analysis.
