Abstract
A data communication device which includes a flash memory, a primary buffer region in the flash memory which has time-sequential information stored therein from earliest to, an auxiliary buffer region in the flash memory which receives and stores primary-buffer storage information to be stored in the primary buffer region during a first condition of the data communication device when the information stored in the primary buffer region is not allowed to be updated, and an information-storage control unit which, when the primary-buffer storage information is stored in the auxiliary buffer region and during a second condition of the data communication device when updating of the information in the primary buffer region is allowed, reads information having a size not more than the storage capacity of the primary buffer region from the information stored in said primary buffer region and the auxiliary buffer region, and which re-stores the information that has been read in the primary buffer region.
