Chip BIN separation method, device and system and storage medium

The invention discloses a chip BIN dividing method, device and system and a storage medium, a mantissa database stores a plurality of mantissa chip data, and the BIN dividing method comprises the following steps: judging whether the mantissa chip data with the same model exists in the mantissa database according to the read model of the current batch of chips, and if the mantissa chip data with the same model exists, determining whether the chip data with the same model exists in the mantissa database; if mantissa chip data with the same model exists, a prompt signal is sent out, batch BIN operation is carried out on the mantissa chips and the current batch of chips, if mantissa chip data with the same model does not exist, BIN operation is carried out on the current batch of chips, then whether the number of the chips with the same BIN item is smaller than a preset value or not is judged, and if the number of the chips is smaller than the preset value, the chips corresponding to the BIN item serve as the man
