    摘要: A memory has a plurality of non-volatile resistive (NVR) memory arrays, each with an associated reference voltage generating circuit coupled by a reference circuit coupling link to a reference line, the reference coupled to a sense amplifier for that NVR memory array. Reference line coupling links couple the reference lines of different NVR memory arrays. Optionally, different ones of the reference coupling links are removed or opened, obtaining respective different average and isolated reference voltages on the different reference lines. Optionally, different ones of the reference circuit coupling links are removed or opened, obtaining respective different averaged voltages on the reference lines, and uncoupling and isolating different reference circuits.

    摘要: A low sensing current non volatile flip flop includes a first stage to sense a resistance difference between two magnetic tunnel junctions (MTJs) and a second stage having circuitry to amplify the output of the first stage. The output of the first stage is initially pre-charged and determined by the resistance difference of the two MTJs when the sensing operation starts. The first stage does not have a pull-up path to a source voltage (VDD), and therefore does not have a DC path from VDD to ground during the sensing operation. A slow sense enable (SE) signal slope reduces peak sensing current in the first stage. A secondary current path reduces the sensing current duration of the first stage.
