Abstract
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.
Claims21
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.
A device which comprises a card connection for connecting a memory card to the device, in which memory card there are several memory locations for storing data, and in which memory card is stored at least one parameter,
- the card 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 card configured so that a specific number of bits is reserved for said at least one parameter, and
- the device further comprising which device an address generator for addressing the memory locations of the memory card, said address generator being configured to use an addressing data stored in the memory card, said addressing data being indicative of at least one addressing method supported.
A memory card
- several memory locations for storing data, and in which memory card is stored at least one parameter, the card 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 card configured so that a specific number of bits is reserved for said at least one parameter, and
- the card further configured to have stored therein an addressing data, said addressing data being indicative of at least one addressing method supported.
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 having means for calculating the number of memory locations of the memory card on the basis of said at least one parameter,
- the system having means for receiving a specific number of bits for said at least one parameter in the memory card, and
- the system further having means for using an addressing data stored in the memory card, said addressing data being indicative of at least one addressing method supported.
A method for addressing the memory locations of a memory card, wherein at least some of said memory locations are for storing data, wherein in order to address a specific memory location the method comprises:
- forming an address,
- storing at least one parameter in the memory card,
- calculating the number of memory locations in the memory card based on said at least one parameter,
- reserving a specific number of bits for said at least one parameter, and
- using an addressing data stored in the memory card, said addressing data being indicative of at least one addressing method supported.
