  • IC card and IC card system having suspend/resume functions
    Patent number: 9004349
    Abstract: An IC card and an IC card system are disclosed in which command processing performance is improved by storing current state data related to a first command upon interruption of an execution cycle for the first command by a second command. Upon completion of the second command, the current state information is reloaded and execution of the first command is resumed.
    Type: Grant

  • Integrated circuit card system and method thereof
    Patent number: 7306140
    Abstract: An integrated circuit card system and method are disclosed. The integrated circuit card system may include a host and a memory card for storing test data transferred from the host. The host may transfer the test data to the memory card when a processing time of the memory card exceeds a reference time. The memory card may calculate the test data transferred from the host, and the host may read out the calculated test data.
