Abstract
A memory card includes: a first memory chip responding to all commands input externally; and a second memory chip responding to commands, among the commands input externally, relevant to reading, programming, and erasing operations with data. Card identification information stored in the first memory chip includes capacity information corresponding to a sum of sizes of the first and second memory chips. The plurality of memory chips of the memory card are useful in designing the memory card with storage capacity in various forms.
Claims36
A memory card comprising:
- a first memory chip responding to all commands input externally;
- and
- a second memory chip responding to commands, among the commands input externally, relevant to reading, programming, and erasing operations with data,
- wherein card identification information stored in the first memory chip includes capacity information corresponding to a sum of sizes of the first and second memory chips.
A memory system comprising:
- a host;
- and
- a multimedia card configured to communicate with the host,
- wherein the multimedia card comprises:
- a first memory chip responding to ail commands input from the host;
- and
- a second memory chip responding to commands, among the commands input from the host, relevant to writing and reading operations with data.
- wherein card identification information stored in the first memory chip includes capacity information corresponding to a sum of sizes of the first and second memory chips.
A method of operating a memory system having a host and a multimedia card including first and second memory chips, the method comprising:
- connecting the multimedia card to the host;
- transferring card identification information to the host from the first memory chip of the multimedia card;
- and
- executing a reading, programming, or erasing operation of the first or/and second memory chips under control by the host,
- wherein card identification information stored in the first memory chip includes capacity information corresponding to a sum of sizes of the first and second memory chips.
A memory system comprising:
- a host;
- and
- a multimedia card bus coupled to the host,
- a first multimedia card communicating with the host through the multimedia card bus and responding to all commands input from the host;
- and
- a second multimedia card responding to commands, among the commands input from the host, relevant to writing and reading operations with data and communicating with the host through the multimedia card bus,
- wherein card identification information stored in the first multimedia card includes capacity information corresponding to a sum of sizes of the first and second multimedia cards.
