A B S "A class of protein polymers called microtubules(W), thought to be responsible for'infornation transfer at the cellular level, are mdeled. Specifically, the electron transfer is modeled as taking place in a bucket brigade fashion, using a specialized matrix of sample and hold (S/H) circuits to retain charge at various Mp sites. A set of pulse transfer waveforms is given, in addition to a sequence of plse trains to describe a pssible directional transfer among sites, based upon genetic, polymerization, or other effects. AbstractAn architecture and implementation of a pulse mode neural network with EE synapse weights, versatile interface capabilities, and on-chip learning will be described.The interface has the ability to input data as 8 bit parallel bytes or as 64 parallel pulse streams. Output can be pulses (O-1OOMhz) or 8 bit parallel data. The pulse mode neuron using nonvolatile electrically erasable programmable weights, and a 100 Mhz sigmoid voltage to frequency converter will be shown.
