Patent ID: 7979623

Claim:
An integrated circuit card system, comprising: a host; a memory core; a plurality of input pins receiving a plurality of commands from the host; a memory card controlling device communicating with the memory core via the plurality of pins; wherein the memory card controlling device activates more than one data transceiving channels concurrently, transceives data through the activated data transceiving channels independently, and includes capabilities of performing two or more functions corresponding to the activated data transceiving channels simultaneously; and wherein the memory card controlling device activates more than one data transceiving channels by dividing the plurality of input pins into input pin groups according to a number of activated transceiving channels, a number of the input pin groups depending on the number of the activated data transceiving channels, each of the input pin groups being assigned to a corresponding data transceiving channel of the activated data transceiving channels wherein the memory card diverts at least one data pin of the plurality of input pins into one of a power supply pin, a ground pin, a command pin and a clock pin when a number of the activated data transceiving channels increases.
