A semiconductor memory control device includes a flexible circuit board having a plurality of panels and folded so that the panels are stacked on one another, a plurality of semiconductor elements mounted on the flexible circuit board, and a package enclosing the flexible circuit board and the plurality of semiconductor elements. A method of mounting semiconductor memory control devices in high density includes mounting a plurality of semiconductor elements on a flexible circuit board, forming an internally mounted module by folding the flexible circuit board in panels that are stacked in multiple layers, and enclosing the internally mounted module in a package. |
