摘要:
A host generates an address array including a header and each start address to perform a data processing operation, which may for example be 4 Kbytes of a random read operation or a random write operation, and transmits a generated address array to a data storage device through a data bus. The data storage device, in the case of a random read operation, outputs each data corresponding to the each start address to the host successively by using the address array. In the case of a random write operation, the data storage device receives each data corresponding to each start address from the host and stores it in a memory core.
摘要:
A method and apparatus for managing digital rights of a portable storage device are provided. The method comprises a device performing authentication together with the portable storage device and sharing an encryption key with the portable storage device as a result of the authentication, requesting a rights object list from the portable storage device, receiving the rights object list from the portable storage device, and processing and displaying the rights object list.
摘要:
A method and an apparatus are provided for managing blocks according to the update type of data in block-type memory. The method includes receiving data to be stored from an application; determining an update frequency of the data; extracting information of nonvolatile memory space in which the data will be stored according to the update frequency of the data; and transmitting information about the data and the space to the nonvolatile memory so that the data is stored in the space using information of the extracted space.
摘要:
A secure booting apparatus and method, in which integrity can be guaranteed when booting with an operating system (OS). The secure booting apparatus includes an OS storing unit, a memory unit, and a control unit. The OS storing unit includes a first region that stores an OS and a second region that stores a check value of an algorithm, the check value corresponding to the OS. The OS is loaded into the memory unit when booting. The control unit calculates a check value based on the loaded OS using the algorithm used to calculate the check value stored in the second region and compares the calculated check value and the check value stored in the second region to determine the integrity of the OS.
摘要:
An apparatus, a method for use in the apparatus, for managing secure data stored in an OTP block. The apparatus includes a secure data recorder that records secure data and its complement, and records new secure data and its complement when a power outage occurs during recording, a secure data check unit that determines the validity of the secure data and its complement, and an error determiner that determines whether the recorded secure data is a partial recording of the new secure data if the secure data is invalid.

The method includes receiving data to be stored from an application; determining an update frequency of the data; extracting information of nonvolatile memory space in which the data will be stored according to the update frequency of the data; and transmitting information about the data and the space to the nonvolatile memory so that the data is stored in the space using information of the extracted space.
摘要:
A method is for adaptively adjusting a user storage region in an entire storage region of a nonvolatile memory system. The method includes a host transmitting a user region information request command to the nonvolatile memory system, the nonvolatile memory system transmitting user region information to the host, the host changing the user region information, the host transmitting a user region information setting command to the nonvolatile memory system, and the nonvolatile memory system controlling a size of the user storage region in response to the user region information setting command.
摘要:
An apparatus and method for authenticating a Non-Volatile Memory (NVM) device are provided. A host device that authenticates the NVM device transmits challenge information for authentication to the NVM device, receives pieces of authentication information in response to the challenge information from the NVM device, and authenticates the NVM device using the pieces of authentication information by the host device. The pieces of authentication information are generated based on the challenge information and secret key information stored in the NVM device.
