PURPOSE: A data storage system and apparatus, and a method of storing image data for a digital camera are provided to reduce the costs by securing a memory incapable of re-writing. CONSTITUTION: A data storage system(10) for storing image data in digital cameras comprises a temporary data storage circuit(24) coupled to receive image data from the camera, and a permanent data storage circuit(20) coupled to receive image data from the temporary data storage circuit. A control circuit(22) is coupled to the temporary data storage circuit and the permanent data storage circuit for effect transfer of image data from the temporary data storage circuit to the permanent data storage circuit upon occurrence of a predetermined event. The permanent data storage circuit is in the form of a write-once non-volatile memory module, which is replaced in the storage system. The temporary data storage circuit is a RAM or Flash memory that temporarily stores image data from the camera when a picture is taken. Then, a user reviews the picture before the picture is permanently stored upon the occurrence of the predetermined event.
