Memory modules and memory devices having memory device stacks, and method of forming same

摘要

A memory module, system and method of forming the same includes a memory module including a plurality of memory devices having a first portion of memory devices cooperatively forming a first rank of memory devices and a second portion of memory devices cooperatively forming a second rank of memory devices. The first and second portions of memory devices are grouped into a plurality of memory device stacks, wherein each of the plurality of memory device stacks includes at least one of the plurality of memory devices coupled to a first portion of a plurality of DQ signals and at least another one of the plurality of memory devices coupled to a different second portion of the plurality of DQ signals.

1. A memory, comprising:
at least one stack of memory devices, including: a first memory device operably coupled to a first plurality of DQ signals; and
a second memory device in a stacked arrangement with the first memory device, the second memory device operably coupled to a second plurality of DQ signals; and a controller operably coupled to the at least one stack of memory devices through the first plurality of DQ signals and the second plurality of DQ signals, wherein the first plurality of DQ signals are different from the second plurality of DQ signals.
