Abstract: A memory module having different types of memory mounted together on a double-sided substrate has a first edge and opposite second edge and includes a plurality of memory controllers, a plurality of flash memories, and a plurality of second memories having a higher signal transmission rate than the flash memories. A socket terminal for connecting the double-sided substrate to a motherboard is formed on the front surface and the back surface of the double-sided substrate on the first edge side; the memory controllers are disposed on the second edge side; the second memories are disposed on the second edge side at positions opposite the positions at which the memory controllers are disposed; and the flash memories are disposed on at least the back surface thereof at positions that are closer to the first edge than are the positions at which the memory controllers and the second memories are disposed.
