Patent number: 9728241Abstract: Non-volatile flip-flops (NVFFs) based circuitries and schemes that incorporate magnetic tunnel junctions (MTJs) are provided to ensure fast data storage and restoration from an intentional or unintentional power outage. The NVFFs based circuitries and schemes also include enhanced scan mode testing capability by exploiting the nonvolatile latch to function as hold latch for delay testing. The NVFFs based circuitries and schemes eliminate additional write drivers, and may operate at an operation frequency of, for example, up to 2 GHz at a supply voltage of 1.1 V and with 0.55 pJ of energy consumption. A near uniform write latency can be achieved through transistor sizing, given write asymmetry of MTJs. NVFFs based circuitries and schemes incorporating data-dependent power gating circuitries can be used to mitigate high static currents generated during retention and back-to-back writing of identical input data.Type: GrantFiled: May 2, 2016Date of Patent: August 8, 2017Assignee: UNIVERSITY OF SOUTH FLORIDAInventors: Swaroop Ghosh, Anirudh Srikant Iyengar, Jae-Won Jang
