Memory card e.g. multi media card, for data storage, has memory management unit providing open and safe interface to access memory blocks and protocol adapter accessing contents of card from host system connected with adapter by interface

摘要

The card has non volatile memories (5, 7) with memory blocks and a memory management unit with an assignment unit assigning memory card-internal applications to the blocks. The unit provides an open and safe interface to access blocks, whereby the interface specifies requirements for protected or unprotected memory. A protocol adapter accesses contents of the card from a host system connected with the adapter using the interface. An independent claim is also included for a method of accessing memory blocks of a memory card.
