摘要
Disclosed is a memory module including: a signal tap and a power tap which are disposed apart from each other on a surface layer of a substrate; and a reference plane layer which is disposed at the lower part of the surface layer by interposing an insulating layer. The shape of the reference plane layer in a module tap region of the memory module is recessed at the lower part of the signal tap but non-recessed at the lower part of the power tap, so signal integrity (SI) and power integrity (PI) are improved together.;COPYRIGHT KIPO 2015
