Abstract
The present disclosure relates to the field of semiconductor integrated circuits and manufacturing technologies thereof, and discloses a method and device for realizing a convolution operation based on an NOR flash storage structure. The NOR flash array has a structure of an array composed of a plurality of NOR flash cells. The convolution operation method includes: storing elements of a convolution kernel matrix into the NOR flash cells; converting elements of an input matrix into voltages and applying the voltages to gate terminals of the NOR flash cells; applying a driving voltage to source terminals of the NOR flash cells; and collecting, via drain terminals of the NOR flash cells, current values of each column to obtain a convolution operation result.
