MICROPROCESSOR CIRCUIT FOR DATA CARRIER AND METHOD FOR PROVIDING ACCESS TO DATA, LOADED IN MEMORY Russian patent published in 2005 - IPC

FIELD: microprocessor circuits engineering, technologies for providing access to data loaded into memory.

SUBSTANCE: circuit has at least one microprocessor, memory for operation system and at least one memory for free programming with individual side software, wherein multiple memory areas are provided with appropriate address spaces, to each of which additional mark corresponds, means, which load the mark, matched by appropriate memory area, into first auxiliary register, and mark of addressed memory area is loaded into second auxiliary register and comparison of first and second auxiliary registers is performed. To each address space of memory area at least one bit series corresponds, containing access privileges, due to which code commands and data can be protected from access for recording from other unauthorized programs.

EFFECT: simplified access to data loaded into memory.
