The pRAM: an adaptive VLSI chip

The pRAM (probabilistic RAM) is a nonlinear stochastic device with neuron like behavior. The pRAM is realizable in hardware, and the third-generation VLSI pRAM chip is described. This chip is adaptive since learning algorithms have been incorporated on-chip, using reinforcement training. The pRAM chip is also adaptive with respect to the interconnections between neurons. Results achieved from a small net of pRAM's performing a pattern-recognition task using reinforcement training are presented.
