Slope detection systems and methods are provided that monitor magnetic tunnel junction (MTJ) resistance switching. A low-overhead, sample-and-hold circuit can be used. Slope detection techniques can reduce or eliminate bit-to-bit process variation, thereby reducing or eliminating variation in oxide thickness. In addition, the need for data and reference current can be obviated compared to related art techniques, thereby increasing sensing robustness.
