Abstract

The standard for calculating memory capacity in modern computing is the bit, and the number of transistors (elements) that make up a node, i.e., the number of bits, is also the unit of modern information communication volume. In contrast, the human brain is made up of neural circuits, and human memory capacity is not based on the number of neural circuits (number of nodes). nerves Circuit complexity far exceeds bit capacity, and modern AI that attempts to replicate the human brain through bit-based computing is inherently wasteful because it handles information in a fundamentally different way. Moreover, bit-based computing is always at the limit of integration. The present invention provides a bit-independent information storage system using a three-dimensional silicon circuit network. [Solution] By switching the electrical connections of non-volatile memory cells distributed in a three-dimensional array, Reproducing the information processing mechanism of the human brain.
