Abstract
A key generator including a first access circuit, a first calculating circuit and a first certification circuit is provided. The first access circuit writes first predetermined data to a first resistive memory cell during a write period and reads a first current passing through the first resistive memory cell after a randomization process. The first calculating circuit calculates the first current to generate a first calculation result. The first certification circuit generates a first password according to the first calculation result.
