摘要： Provided are a secure multimedia card (secure MMC) and a memory card system having the same. The memory card system may include a host, and a secure MMC having a user data area accessed by a normal command and a restricted area accessed by a secure command, wherein the user data area in communication with the host stores user data and the restricted area stores access restriction data. The restricted area may be accessed in the secure MMC even though the interface unit in the host does not support commands requesting the access to the restricted area in the secure MMC.
