Method for addressing a memory card, a system using a memory card, and a memory card

摘要

The present invention relates to a method for addressing the memory locations of a memory card. There are several memory locations in a memory card for storing data, in which case in order to address a specific memory location an address is formed. At least one parameter is stored in the memory card, on the basis of which parameter the number of memory locations of a memory card can be calculated, and a specific number of bits is reserved for said at least one parameter. In the method, two or more memory locations are addressed with one address, and/or the number of bits that can be used in an address is increased. The invention also relates to a system and a memory card in which the method is applied.

主权项

1. A system comprising:
a memory card having several memory locations for storing data, and in which memory card is stored at least one parameter, the system configured so that the number of memory locations of the memory card can be calculated on the basis of said at least one parameter, the system configured so that a specific number of bits is reserved for said at least one parameter in the memory card, and the system further configured to use an addressing data stored in the memory card, said addressing data being indicative of at least one addressing method supported, wherein the addressing data indicates either a basic addressing method or an expanded addressing method, and wherein the expanded addressing method enables the addressing of data in a larger number of memory locations than the basic addressing method.
