Abstract
A memory module and a method of mounting memory devices on a PCB to form the memory module substantially reduce unnecessary routing space and improve signal attenuation characteristics. In the method of mounting and sequentially connecting at least two memory devices on a printed circuit board(PCB) having an axis of elongation to form a memory module, at least one of the memory devices is mounted on at least one face of the PCB so that a base line along an longitudinal axis of the at least one memory device lies at an acute angle with respect to the axis of elongation of the PCB.
