Abstract
A communication apparatus comprising a RAM having a back up power source; a recording/reproducing portion having a flash EEPROM, for recording at least a piece of information in the EEPROM having a plurality of sectors and for reproducing the information stored therein, each sector having a sector number and a given capacity and being independently erasable; and a recording control portion, responsive to a ring signal from a telephone line or a command signal, for receiving the information, detecting a data amount of the received information, for storing the information in at least one sector, for detecting a sector number of the at least one sector used to store the control data in accordance with the detected data amount, and for storing the detected sector number in the RAM. This apparatus may further comprise a ring signal detector for producing the command signal in response to a ring signal from a telephone line; and an I/F circuit responsive to the command signal for communicating with the telephone line; or a reproducing controller for selectively reproducing information from the EEPROM using the sector numbers stored in the RAM; or an erasing control portion for selectively erasing recorded information in the EEPROM using the sector numbers stored in the RAM. The information may include sound or image information.
