Abstract
A memory chip includes a plurality of pins. The plurality of pins are divided into two rows for arrangement on the opposite sides of the memory chip. All data I/O pins are arranged on one side surface (in the same row) of a package. In the case of forming a memory module, each chip is arranged such that the data I/O pins may be nearest to a center line of a module substrate parallel to a connect pin group. Thereby, interconnections between the respective memory chips and the connect pins have substantially equal lengths.
