Abstract

A novel microchip implementation for an associative neuron group is presented. This microchip is intended for human-like cognitive systems where information is processed via links between distributed representation signal arrays. In this study a microchip containing 8 associative neurons and 128 synaptic connections was realized by 0.35 μm CMOS process. The synaptic weights have been implemented using a customized analog nonvolatile EEPROMs. Measurements show that the presented ideas work and the neuron group is able to associate signal arrays together as intended and the proposed analog EEPROM structure is operating in an accurate and reliable manner even using a standard CMOS technology
