Abstract
A memory module capable of changing the generation of semiconductor memory devices by changing the design of a unit board without changing the design of a mother board. The mother board has connection terminals having an ability of connecting with first and second generation type unit boards, so that even when a connection terminal location is changed as a result of the generation change of the semiconductor memory devices, the next unit board can be connected to the mother board by selecting an appropriate terminal from connection terminals on the mother board.
