Pulse Coded Biologically Motivated Neural-Type MOS Circuits.

摘要

VLSI designs of SYNETSIM Modules and their extensions VLSI Designs for the major pools of SYNETSIM were made and MOSIS fabrications carried out. From these some new elements were designed and in most cases fabricated via MOSIS, the key ones being a neural type arithmetic unit, and adjustable MOSFET transistor convenient for weight setting, and considerable improvement in the neural type cell being used in many of our pulse coded networks. Because capacitors take a large amount of the VLSI chip area, a new capacitance multiplier was designed and fabricated. Using the pools a realization for ART1 memories was obtained. Means for realizing long term potentiation were investigated which are leading to a new concept of memory based upon the pools and their incorporation of second messenger effects.
