Abstract
A deep neural network based on analog FLASH computing array, includes a number of computing arrays, a number of subtractors, a number of activation circuit units and a number of integral-recognition circuit units. The computing array includes a number of computing units, a number of word lines, a number of bit lines and a number of source lines. Each of the computing units includes a FLASH cell. The gate electrodes of the FLASH cells in the same column are connected to the same word line. The source electrodes of the FLASH cells in the same column are connected to the same source line, and the drain electrodes of the FLASH cells in the same row are connected to the same bit line. Each of the subtractors includes a positive terminal, a negative terminal and an output terminal.
