  • Publication number: 20170337466
    Abstract: An artificial neural network device that utilizes one or more non-volatile memory arrays as the synapses. The synapses are configured to receive inputs and to generate therefrom outputs. Neurons are configured to receive the outputs. The synapses include a plurality of memory cells, wherein each of the memory cells includes spaced apart source and drain regions formed in a semiconductor substrate with a channel region extending there between, a floating gate disposed over and insulated from a first portion of the channel region and a non-floating gate disposed over and insulated from a second portion of the channel region. Each of the plurality of memory cells is configured to store a weight value corresponding to a number of electrons on the floating gate. The plurality of memory cells are configured to multiply the inputs by the stored weight values to generate the outputs.

  • Patent number: 8493138
    Abstract: A memcapacitive device includes a first electrode having a first end and a second end and a second electrode. The device has a memcapacitive matrix interposed between the first electrode and the second electrode. The memcapacitive matrix has a non-linear capacitance with respect to a voltage across the first electrode and the second electrode. The memcapacitive matrix is configured to alter a signal applied on the first end by at least one of a) changing at least one of a rise-time and a fall-time of the signal and b) delaying the transmission of the signal based on the application of a programming voltage across the first electrode and the second electrode.

  • Publication number: 20120074378
    Abstract: A memory element is provided that includes a first electrode, a second electrode, and an active region disposed between the first electrode and the second electrode, wherein at least a portion of the active region comprises an elastically deformable material, and wherein deformation of the elastically deformable material causes said memory element to change from a lower conductive state to a higher conductive state. A multilayer structure also is provided that includes a base and a multilayer circuit disposed above the base, where the multilayer circuit includes at least of the memory elements including the elastically deformable material.
