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.
Claims20
A memory module having backup function, comprising:
- a memory connector having a plurality of pins, adapted to be connected to an original memory socket of a printed circuit board;
- a backup memory having capacity equivalent to that of a source memory, connected to a main system through a plurality of said pins of the memory connector;
- a switching means for selecting a backup memory or a source memory;
- and
- a memory socket for inserting a source memory.
A memory module having backup function, characterized by comprising:
- a memory connector consisting of an inner support part and a lead part, the inner support part having a configuration substantially equivalent to that of a source memory, a hollow chip mounting part being provided in the inner support part for mounting a specific chip, the lead part being adapted to be connected to an original memory socket for connecting with the base board of a backup system;
- a switching means, for selecting a backup memory or a source memory;
- a backup memory having capacity equivalent to that of the source memory, connected between the switching means and the main system through the pins of the memory connector;
- a memory socket for inserting a source memory, connected to the main system through the switching means;
- and
- a base board on which a specific chip is mounted, having two or more layers of circuits, one layer of circuit being connected to the memory connector, and the other layer of circuit being connected to the backup memory and the memory socket.
