Abstract
In some embodiments, the present application provides a memory device. The memory device includes a first read bias transistor, a first pull-up read-enable transistor, an MTJ memory cell, a first pull-down read-enable transistor, and a first non-linear resistance device. The first non-linear resistance device is coupled in series and between the first pull-up read-enable transistor and the first read bias transistor. The first non-linear resistance device is configured to provide a first resistance when applied a first voltage and a second resistance greater than the first resistance when applied a second voltage smaller than the first voltage.
