The invention discloses a storage-chip classification method, classification device and classification system. The method includes: acquiring identification information of a to-be-detected storage chip, and acquiring a detection instruction, which corresponds to the to-be-detected storage chip, according to the identification information; then carrying out quality detection on the to-be-detected storage chip according to the detection instruction to acquire detection result parameters; and then classifying the to-be-detected storage chip according to the detection result parameters to acquirea quality level corresponding to the to-be-detected storage chip. The corresponding detection instruction is acquired according to the identification information of the to-be-detected storage chip, thus a quality detection process of the to-be-detected storage chip is accelerated, and detection efficiency is improved; and at the same time, the to-be-detected storage chip is classified and the quality level corresponding to the to-be-detected storage chip is determined according to the acquired detection result parameters, thus high accuracy of a detection result is ensured, additional costs added by subsequent reworking are avoided, and economic benefits are improved.
