Abstract

See full text

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.
