Memory card and memory system having the same

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.

1 . A memory card comprising:
 a first memory chip responding to commands input externally that are relevant to reading, programming, and erasing operations with data; and   a second memory chip responding to commands input externally that are relevant to reading, programming, and erasing operations with data,   wherein card identification (ID) information is stored in the first memory chip and the second memory chip, wherein the card ID information includes capacity information corresponding to a sum of sizes of the first and second memory chips,   wherein the first memory chip includes a first flash memory, and a first controller operating to control the first flash memory, and   wherein the second memory chip includes a second flash memory and a second controller operating to control the second flash memory,   wherein only one of the memory chips is set as a primary and only the memory chip set as primary additionally responds to a command input externally for card identification.
