The invention provides a method, a device, a system and equipment for realizing function calculation based on storage and calculation integration, and a storage medium, which can be applied to the technical field of artificial intelligence. The method comprises the following steps: for a first power item in a first Taylor expansion in a first to-be-calculated function, adjusting a first conductivity value of a variable resistor on a word line corresponding to the first power item in the semiconductor memory device according to a coefficient value of a first coefficient corresponding to the first power item; inputting a pulse voltage to a word line passing through a variable resistor in the semiconductor memory device according to the value of the first power term to obtain a first current output by the bit line; performing analog-to-digital conversion on the first current to obtain a first current value corresponding to the first current; and determining a first calculation result of the first to-be-calculate
