Abstract
A method of operating a memory device, a first setting signal is received by a first memory device among a plurality of memory devices. The first memory device has a first storage capacity, and the memory devices may be connected to one another by a single channel. A second setting signal is received by a second memory device among the plurality of memory devices. The second memory device has a second storage capacity different from the first storage capacity. N refresh operations are performed by the first memory device based on a first refresh command and the first setting signal during a first refresh period. M refresh operations are performed by the second memory device based on a second refresh command and the second setting signal during a second refresh period. A duration of the second refresh period is substantially the same as a duration of the first refresh period.
