ABSTRACT:
A memory card design which allows for stackable memory cards so that a computer system's memory capabilities can be expanded by connecting a first memory card to sockets of the computer system's motherboard and then stacking subsequent memory cards on top of this first memory card. The memory card design includes connector sockets on a top surface of the card which allow for another card to be plugged into these sockets. Also, a presence detect serial EPROM and steer and encode logic are provided to assign a unique system address to each presence detect. The serial presence detect address select wiring are offset within the stack as are RAS lines so that all lines do not have to be hard-wired through each card of a stack of the present invention.
