    摘要: An adaptable current mirror includes first and second MOS transistors. The first MOS transistor has its gate connected to its drain. A MOS capacitor structure is connected in series between the gate of the first MOS transistor and the gate of the second MOS transistor. Electrons may be placed onto and removed in an analog manner from a floating node associated with the second MOS transistor, usually the gate of the transistor, by application of first and second electrical control signals. A first electrical control signal controls the injection of electrons onto the floating node from an electron injection structure and the second electrical control signal controls the removal of electrons from the floating node by an electron removal structure. A plurality of adaptable current mirrors communicating with a plurality of current-carrying lines may be employed for indicating the output of the one of the plurality of current-carrying lines through which the most current is flowing.

A polysilicon floating gate is separated from the surface of the silicon substrate by a layer of gate oxide.

    摘要: A synaptic array according to the present invention comprises a plurality of electrically-adaptable elements. Electrons may be placed onto and removed from a floating node in each electrically adaptable element associated with at least one MOS insulated gate field effect transistor, usually the gate of the transistor, in an analog manner, by application of first and second electrical control signals generated in response to an adapt signal. The inputs to all synaptic elements in a row are connected to a common row input line. Adapt inputs to all synaptic elements in a column are connected together to a common column adapt line. The current supplied to all amplifiers in a column is commonly provided by a sense line. In order to adapt the synaptic elements in the M row by N column matrix of the present invention, the voltages to which a given column n of the matrix is to be adapted are placed onto the input voltage lines, and the synaptic elements in column n are then simultaneously adapted by assertion of an adapt signal on the adapt line for column n. The vectors of input voltages for adapting successive columns may be placed sequentially onto the row input voltage lines and used to adapt the columns of synaptic elements by assertion of the adapt signals on the appropriate column adapt lines until the entire array is electrically adapted. After each synaptic element has been adapted, the current flowing through it will be maximized when the voltage at the input of the synaptic element equals the voltage to which the synaptic element has been adapted. An electrically adaptable winner-take-all circuit has its inputs connected to the column-sense lines of the array.

    摘要: A weight-storage and weight-adjustment circuit includes a first hot electron injection device coupled to a first floating gate and a second hot electron injection device coupled to the second floating gate. The floating gates are associated with two series connected MOS transistors. The first and second hot electron injection devices comprise gated lateral bipolar transistors. The weight may be decreased by injecting hot electrons from the first hot electron injection device onto the first floating gate to decrease the first analog voltage and increased by injecting electrons from the second hot electron injection device onto the second floating gate to decrease the second analog voltage. Circuitry are provided to periodically adjust the absolute voltage levels on the first and second floating gates to prevent them from becoming too negative over time. First and second electron tunneling devices are coupled to the first and second floating gates, respectively, to simultaneously adjust the voltages stored on the floating gates to keep them within a desired voltage range.
