Abstract
A provided memory device is compatible with a mono-rank or multi-ranks. A plurality of memory layers are stacked in the memory device. The memory device receives an address signal and chip select signals in response to a chip identification signal and a mode signal used to determine a mono-rank or multi-ranks. The plurality of memory layers operate as the mono-rank accessed by the address signal, or operate as the multi-ranks accessed by the chip select signals.
