  • Patent number: 11522133
    Abstract: Subject matter disclosed herein may relate to fabrication of correlated electron materials used, for example, to perform a switching function. In embodiments, processes are described in which a correlated electron material film may be formed over a conductive substrate by converting at least a portion of the conductive substrate to CEM.
    Type: Grant
    Filed: February 25, 2019
    Date of Patent: December 6, 2022
    Assignee: Cerfe Labs, Inc.

  • Patent number: 10873025
    Abstract: Subject matter disclosed herein may relate to fabrication of a correlated electron material (CEM) switch. In particular embodiments, formation of a CEM switch may comprise depositing metal layers, such layers of a transition metal, over a conductive substrate. Dopant layers may subsequently be deposited on the layers of the transition metal, followed by annealing of the layers of transition metal and dopant layers. Responsive to annealing, dopant from the dopant layers may diffuse into the one or more layers of transition metal, thereby forming a CEM.

  • Patent number: 8816719
    Abstract: A re-programmable antifuse field programmable gate array (FPGA) integrated circuit, the FPGA comprising: a plurality of CeRAM resistive switching elements forming a connection block, the switching elements capable of being switched from a conductive (ON) state to a non-conductive (OFF) state and back to a conductive (ON) state; a plurality of logic elements forming a logic block; and a programming circuit for turning the CeRAM switching elements OFF and ON to connect the logic elements to form the FPGA.
