Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2021177394
Kind Code:
A
Abstract:
To provide a semiconductor device and an electronic apparatus including the semiconductor device.SOLUTION: In a module 100, a neuron circuit NU can switch the functions of an input neuron circuit and a hidden neuron circuit. An error circuit EU can switch the functions of a hidden error circuit and an output neuron circuit. A switch switches the connection between the neuron circuit, a synaptic circuit SU, and the error circuit. The synaptic circuit has an analog memory that stores data corresponding to the coupling strength between the input neuron circuit and the hidden neuron circuit or between the hidden neuron circuit and the output neuron circuit, a writing circuit that changes the data in the analog memory, and a weighting circuit that outputs an output signal obtained by weighting an input signal according to the data in the analog memory. The analog memory is composed of a transistor using an oxide semiconductor with an extremely low off-state current.SELECTED DRAWING: Figure 1
