Zusammenfassung:A semiconductor device for achieving consistency of data is provided. The process performed by the semiconductor device includes a step of compressing data to generate compression information representing compressed data and the amount of information, a step of accessing management data for controlling access to a memory area, a step of permitting writing to a memory area in units of a predetermined data size based on the fact that the management data indicates that the accessed area is not exclusively allocated to another compression/expansion module, a step of writing data to update management data, a step of permitting reading from the area in units of the data size based on the fact that the management data indicates that the accessed area is not exclusively owned to another compression/expansion module, and a step of reading the compressed data and the compressed information from the area in units of the data size.
