FIELD: information technology.SUBSTANCE: invention relates to information processing. Information processing device, having read-only memory, including executable instructions or data, processor for addressing read-only memory and retrieval of executable instructions or data via bus, a CAM device connected to bus and configured to compare address requested by processor, with elements of vector of addresses, which must be corrected, and if address requested by processor, coincides with one of elements of vector, be in processor a substitution performed instruction or data instead of executed instructions or data addressed to processor in read-only memory; wherein said CAM device is MRAM device containing multiple MRAM memory devices, wherein each cell storage MRAM device comprises at least one magnetic tunnel junction device itself is configured to interrupt processor, if address requested by processor coincides with one of elements of vector of addresses, which must be corrected to prevent reading performed instructions data addressed to processor.EFFECT: technical result is enabling patching in specific assembly instructions or group thereof without increasing volume of code or delaying program, when no corrections are made.5 cl, 3 dwg |
