  • Patent number: 12294367
    Abstract: A level shifter includes a cross-coupled transistor pair, first through third biased transistor pairs and a differential input pair sequentially coupled in series, and further includes a sub level shifter. The first biased transistor pair is controlled by a first reference voltage. The second biased transistor pair is controlled by a pair of differential control voltages. The third biased transistor pair is controlled by a second reference voltage lower than the first reference voltage. The differential input pair is controlled by a pair of differential input voltages. The sub level shifter generates the differential control voltages according to the differential input voltages and the first and second reference voltages. The differential control voltages are switched between the first and second reference voltages. The level shifter outputs a pair of differential output voltages through inverted and non-inverted output terminals coupled with the second biased transistor pair.

    Abstract: A random code generating method for the magnetoresistive random access memory is provided. Firstly, a first magnetoresistive random access memory cell and a second magnetoresistive random access memory cell are programmed into an anti-parallel state. Then, an initial value of a control current is set. Then, an enroll action is performed on the first and second magnetoresistive random access memory cells. If the first and second magnetoresistive random access memory cells fail to pass the verification action, the control current is increased by a current increment, and the step of setting the control current is performed again. If the first and second magnetoresistive random access memory cells pass the verification action, a one-bit random code is stored in the first magnetoresistive random access memory cell or the second magnetoresistive random access memory cell.
