PRECISE PROGRAMMING METHOD AND DEVICE FOR ANALOG NEURAL MEMORY IN ARTIFICIAL NEURAL NETWORK

Title:

PRECISE PROGRAMMING METHOD AND DEVICE FOR ANALOG NEURAL MEMORY IN ARTIFICIAL NEURAL NETWORK

Document Type and Number:

Japanese Patent JP2023169170

Kind Code:

A

Abstract:

To provide a precise programming algorithm and device for precisely and rapidly depositing precise amounts of charge on a floating gate of a non-volatile memory cell in a vector-by-matrix multiplication (VMM) array in an artificial neural network.SOLUTION: A method of programming a non-volatile memory cell includes: programming all cells to a "0" state; erasing all cells to an intermediate weak erase level; executing a hard program for adding electrons to a floating gate of the cell to a very deep programmed state on all non-selected cells; executing a coarse programming method on the selected cell; executing the precision programming method on the selected cell; and programming each selected cell with the exact value desired.SELECTED DRAWING: Figure 33A
