Data storage method and system of solid-state memory

The invention relates to the technical field of data compression, in particular to a data storage method and system for a solid-state memory, and the method comprises the steps: obtaining to-be-compressed data; constructing an FP tree according to the to-be-compressed data; according to the position of each character in the corresponding node in the FP tree, and in combination with the occurrence frequency of each character in the to-be-compressed data, obtaining the coding priority of each character; obtaining a plurality of character pairs, and obtaining the matching degree of the character pairs in combination with corresponding nodes in the FP tree; obtaining a target character pair according to the matching degree of the character pair, and endowing the target character pair and a compressed code of the character; and compressing the to-be-compressed data by utilizing the target character pair and the compression codes of the characters, and storing a compression result into a solid-state memory.
