ABSTRACT:
A stackable memory system for minimizing the stub lengths of the memory data bus and data skew. The invention provides a memory controller, a memory connector, a data bus, a first stackable memory module and a terminator plate. The data bus electrically connects the controller to the memory connector. The first stackable memory module is mechanically and electrically connected to the memory connector. The terminator plate is adapted to substantially reduce reflections to the data bus and is electrically connected to the data bus through the first stackable memory module. Additional, the memory system may be expanded by adding stackable memory modules substantially similar to the first stackable memory module to the stackable memory system between the first memory module and the terminator plate. Each stackable memory module may include memory chips each of which has trace lines connecting the memory chip to a module connector. Each of the trace lines is substantially equal in length and connects to a single side of the memory chip.
