				 Abstract   

    We describe how current models of computation in the brain can be
    physically implemented using VLSI technology.  This includes modeling
    of sensory processes, memory, and learning.  We have fabricated a test
    chip in 2 micron CMOS that can perform supervised learning in a manner
    similar to the Boltzmann machine.  The chip learns to solve the XOR
    problem in a few milliseconds.  Patterns can be presented to it at
    100,000 per second.  We also have demonstrated the capability to do
    unsupervised competitive learning as well as supervised learning.
