摘要
This paper describes a floating-gate MOSFET device that can be used as a precision analog memory for neural network LSI'S. This device has two floating gates. One is charge-injection gate with a Fowler-Nordheim tunnel junction, and the other is a charge-storage gate that operates as a MOSFET floating gate. The gates are connected by high resistance, and the charge-injection gate is small so that its capacitance is much less than that of the charge-storage gate. By applying control pulses to the charge-injection gate, it is possible to charge and discharge the MOSFET floating gate in order to modify the MOSFET current with high resolution over 10-bits. The charge injection can be carried out without much disturbing the MOSFET output current with high voltage control pulses. This device is useful for on-chip learning in analog neural network LSI's.
