Abstract
A memory module includes arrays of memory devices each having a data bus coupled to the data bus of a host memory channel by means of a switching tree. The switching tree is a tree of multiplexers that are controlled to couple the data lines of a single array to the data bus. In some embodiments, a first portion of the chip enable (CE) lines of a memory module are used to enable arrays of memory devices and a second portion are used to control the switching tree. The first portion may control a switching tree coupling the first portion to the enable inputs of the arrays.
