Abstract
A stack package including a first semiconductor chip and second semiconductor chip, the first semiconductor chip including first data I/O pads for transmitting data I/O signals, a first flag pad for receiving a flag signal, and a first buffer for controlling a switching operation between the first data I/O pads and an internal circuit of the first semiconductor chip. The second semiconductor chip includes second data I/O pads for transmitting the data I/O signals, a second flag pad for receiving the flag signal, and a second buffer for controlling a switching operation between the second data I/O pads and an internal circuit of the second semiconductor chip. The first data I/O pads are electrically connected to respective ones of the second data I/O pads through first wires, and the first flag pad is electrically connected to the second flag pad through a second wire. Related methods are also provided.
