A method for controlling a resistive random access memory (ReRAM) is proposed. The method calculates a number of a bit value of a data when the data is to be written to the resistive random access memory. Each bit of the data is flipped and the data is written to the ReRAM if the number of the bit value is greater than a half of a length of the data. The data as it original is written to the ReRAM if the number of the bit value is less than a half of the length of the data.

An energy-efficient nonvolatile microprocessor includes a processing core, a nonvolatile flip-flop array, a set of nonvolatile interconnections, and a store-enable register. When a power source is recovered to a stable state, the processing core determines whether data of nonvolatile registers is not transmitted before power-off. If yes, the processing core executes programmable recovery entry decision to avoid recovery failures for different applications. The processing core has plural system states divided into programmer visible states and programmer invisible states. The nonvolatile interconnections are connected between the processing core and the nonvolatile flip-flop array. When the power source is unstable, the processing core only stores the programmer visible states into the nonvolatile flip-flop array and, at the same time, only stores the system states of the peripheral modules corresponding to the bits of the store-enable register that are set to be 'true' into the nonvolatile flip-flop array.
