  • Memory module having backup function
    Patent number: 6476473
    Abstract: The present invention relates to a backup module for a standard memory chip, more especially a standard memory chip (for example, DIP, QFJ and PLCC packages) having high-density pins for the backup of a personal computer. If the standard memory chip is out of order, the backup module according to the present invention can take the place of the standard memory chip. By switching between two or more chips, the capacity of the memory can be effectively increased as a whole and the content (program or data) of the memory can be easily optimized.
