Abstract :
The nonlinear model of the functional properties of the hippocampal formation has been developed. The architecture of the proposed hardware implementation has a topology highly similar to the anatomical structure of the hippocampus, and the dynamical properties of its components are based on experimental characterization of individual hippocampal neurons. The design scheme of a analog cellular neural network has been extensively applied. By using a 1-μm CMOS technology, the 5×5 neuron array with some testing modules has been designed for fabrication. According to the SPICE-3 circuit simulator, the response time of each neuron with memorizing 4 time units is around 0.5 μsec
