A combination cellular telephone and sound storage device has a traditional cellular telephone having a microphone that is operably connected to a transmitter/receiver which is operatively connected to a speaker. The invention further include a sound storage device, preferably a non-volatile analog memory chip, that is also operatively connected to both the microphone and speaker. The circuit connecting the memory chip to the microphone is controlled by a record switch. The record switch is operatively controlled by a record button, thereby allowing the user to record verbal notes made into the microphone during the course of the conversation. The memory chip is operatively connected to the speaker through a play switch. The play switch is operatively controlled by a play button, thereby allowing the user to replay the verbal notes recorded on the microphone. In its preferred embodiment, the combination further includes a mute button so that the user can record verbal notes without the other person being able to hear the verbal notes. The invention enables the method of using the combination to make verbal notes while talking on the cellular phone.
