Abstract:
Systems and methods for multiple-time programmable (MTP) devices. An MTP device includes a magnetic tunnel junction (MTJ) device programmable to a plurality of states based on voltage applied across the MTJ device. The plurality of states include a first resistance state corresponding to a first binary value stored in the MTJ device based on a first voltage, a second resistance state corresponding to a second binary value stored in the MTJ device based on a second voltage, a third resistance state corresponding to a breakdown of a barrier layer of the MTJ device based on a third voltage, and a fourth resistance state corresponding to an open fuse based on a fourth voltage.
