Abstract
In a memory controller according to the present invention, an external I/F unit receives ID information associated with data from the outside of a non-volatile memory, and a recording controller manages a recording position of the data in the non-volatile memory based on the ID information, so that an amount of time necessary for the retrieval of rights information based on the ID information is reduced.
Claims27
A memory controller connected to a non-volatile memory for writing data and ID information associated with the data in the non-volatile memory and reading the data and the ID information from the non-volatile memory based on an access instruction supplied from outside of the non-volatile memory, comprising:
- an external I/F unit for receiving the ID information associated with the data from the outside of the non-volatile memory;
- and
- a recording controller for managing a recording position of the data in the non-volatile memory based on the ID information.
A data management method for writing data and ID information associated with the data in a non-volatile memory based on an access instruction supplied from the outside of the non-volatile memory and reading the data and the ID information from the non-volatile memory, comprising:
- a first step for receiving the ID information associated with the data from the outside of the non-volatile memory;
- and
- a second step for managing a recording position of the data in the non-volatile memory based on the received ID information.
