PERMANENT COMPUTING METHOD USING A NON-VOLATILE RANDOM ACCESS MEMORY TO EXECUTE A PROGRAM IN THE NON-VOLATILE RANDOM ACCESS MEMORY, AND A SYSTEM THEREOF

摘要

PURPOSE: A permanent computing method using a non-volatile random access memory and a system thereof are provided to give permanence to a program.;CONSTITUTION: A non-volatile RAM(Random Access Memory)(120) does not lose stored even though a power is disconnected, enables a byte unit based address access, and stores register and state values while executing a program. When a power is resupplied after disconnection, a processor(110) calls up the register and state values and restores the current state into a state before the power disconnection. A power disconnection detection unit detects an event of which supplied power is lower than a critical value. When sensing the event, the non-volatile RAM stores the register and state values.;COPYRIGHT KIPO 2010
