Abstract
A stack memory device includes a base chip, and a core chip stacked with the base chip and electrically connected to the base chip. In the present disclosure, the base chip includes a transmission/reception circuit configured to receive write data, a write valid signal, and a transmission write clock signal, a serialization/parallelization circuit configured to receive the write data, based on the write valid signal in synchronization with the transmission write clock signal and to generate a parallelized input packet from the write data, and a data transmission control circuit configured to decode the parallelized input packet to extract first internal data that is stored in the core chip when a write operation is performed on the core chip from the parallelized input packet.
