Memory module including plural memory devices and data register buffer

摘要

Disclosed herein is a memory module that includes a module substrate, data connectors, memory devices, and data register buffers. A first main surface of the module substrate has first and second memory mounting areas. One of the first and second main surfaces of the module substrate has a register mounting area located between the first and second memory mounting areas in a planner view. The memory devices include a plurality of first memory devices that are mounted on the first memory mounting area and a plurality of second memory devices that are mounted on the second memory mounting area. The data register buffers are mounted on the register mounting area. The data register buffers transfers write data supplied from the data connectors to the memory devices, and transfers read data supplied from the memory devices to the data connectors.
