An analogue neural network using MCM technology

Describes a large analogue neural network implemented using multichip module (MCM) technology to provide interchip connections. An array of eight synapse chips, each containing 2500 synapses, is connected to a neuron chip on an MCM to implement a (150, 100, 50) network containing more than one million transistors. MCM technology enables a higher synapse density to be achieved and benefits which include smaller area and reduced parasitics can be enjoyed. The MCM is under construction, and its completion will provide a large analogue neural network in a single package which can be used for many applications which require such networks
