Claim One:
1. A neuromorphic computing device, comprising: at least one input; at least one output; and a plurality of synapse circuits electrically interconnecting said at least one input to said at least one output, wherein; said synapse circuit further comprises an input; an output; and a variable resistance element having an input and an output, wherein said variable resistance element controls the connection strength between said synapse circuits; and wherein said variable resistance element further comprises a transistor biased in its linear operating region, wherein said output of said synapse circuit outputs a signal SO(SI, Vm) according to the relationship O ⁡ ( S ⁢ ⁢ I , V m ) = - 4 * [ μ n ⁢ C ox ⁢ W L ⁢ ( ( V m - V th ) ⁢ S ⁢ ⁢ I - SI 2 ) 2 ⁢ R ] + 2 ⁢ V wherein SI is the input to said synapse in voltage units; V m is a biasing weight voltage of said transistor; W is the width of said gate of said transistor; L is the length of said gate of said transistor; C ox is the gate oxide capacitance of said transistor; R is the value of a biasing resistor used to control the potential output of said synapse; V th is the threshold voltage of said transistor; and μ n is electron mobility of said transistor.
