Sequential EEPROM writing apparatus which sequentially and repetitively replaces a head position pointer with a last position pointer |
摘要 |
A storage device incorporating an electrically erasable read only memory (EEPROM) or other data storage device having a limited number of total times of rewriting, has its useful like extended by the method of storing a pointer corresponding to the capacity of the memory, which pointer identifies a start position in the data storage device at which rewriting is to occur, and incrementing the pointer sequentially with each writing of the data storage device. The method and associated apparatus may be used to maintain a record of on-time of electronic apparatus, and/or to maintain data for correcting the white balance of a video camera under various light conditions.
