Method and system for allocating, accessing and de-allocating storage space of a memory card

Abstract

A memory card includes an anti-tamper module having at least one first non-volatile memory module and a processor for executing a plurality of applications. The memory card also includes at least one second memory module external to the tamper-resistant module and a memory management unit that allocates memory blocks from the first or second memory module to applications.

Description

technical field [0001] The present invention relates generally to memory cards, and more particularly, to methods and systems for allocating, accessing, and deallocating storage space of memory cards. Background technique [0002] Non-volatile memory cards are increasingly replacing other forms of data storage. These non-volatile memory cards are particularly beneficial for mobile applications because they provide high data capacity using only limited space and are insensitive to ambient magnetic fields and mechanical failures. [0003] Unlike conventional storage media such as optical discs or magnetic tapes, memory cards include a card internal controller that controls access to the card's internal memory modules. This allows one to securely store data on a memory card without exposing the data to every host system connected to the memory card. [0004] It is well known to use memory cards to securely store sensitive data for applications such as copyright protected musi...

AI Technical Summary

Problems solved by technology

[0007] A disadvantage of the known prior art is that the allocation of protected and unprotected data is fixed by the physical arrangement of the memory card, the protected data being stored inside the TRM and the unprotected data being stored in another non-volatile memory module
