  • Patent number: 9742403
    Abstract: A state-retaining logic cell may include a plurality of inverters, an output node non-volatile (NVM) storage cell, and an input node NVM storage cell. The plurality of inverters may include a feed-forward inverter and a feed-back inverter disposed in a back-to-back arrangement. The output node NVM storage cell may include first and second terminals, where the first terminal is connected adjacent an output node of the feed-forward and the feed-back inverters, and the second terminal is connected to a programming rail. The input node NVM storage cell may include first and second terminals, where the first terminal is connected adjacent an input node of the feed-forward and the feed-back inverters, and the second terminal is connected to the programming rail.

  • Patent number: 9601195
    Abstract: The present disclosure provides a memory cell that includes a resistive memory element disposed between a first conductor and a second conductor, the first conductor and the second conductor configured to activate the resistive memory element. The memory cell also includes a diode disposed in parallel with the memory element between the first conductor and the second conductor.

  • Patent number: 9490010
    Abstract: A method for setting resistance states of a first and a second resistive memory element (RME) is disclosed. The method may include coupling, via a common node, a first RME to a second RME. The method may include setting the first RME to either a high voltage resistance state or a low voltage resistance state. The method may include setting the second RME to a different state relative to the state of the first RME, wherein setting the second RME is substantially simultaneous with setting the first RME.
