Abstract

This article describes the design of an associative (content addressable) memory which can be implemented in silicon technology. It is electrically programmable and designed to function as a read mostly memory. In * it is shown that a complex network of interconnections of non-linear switches can mimic the behavior of a spin glass. This means that the network achieves a finite number of quasi-stable states. That number is much smaller than the total number of interconnections possible. In other words the possible amount of information which can be remembered by such a network is far smaller than with a conventional memory. However, when only partial information is given to the system, the network will settle into one of these quasi-stable states.
