Abstract
By using the combination of a pre-existing command signal that is common to two memory devices and a non-shared command signal that is applied individually to each of the devices, embodiments of the invention may operate in a mirror mode, thereby preventing unwanted signal degradation due to stub loads. Because embodiments of the invention do not require additional dedicated pins and/or pads compared to the conventional art, it is possible to achieve mirror mode operation in a smaller device package.
