Abstract

This invention provides a device and control method that can be connected to two or more different devices via different interfaces, thereby more clearly defining the role of a hub for mediating when multiple different interfaces are used within a memory. [Solution] The method includes the steps of: receiving a first clock signal from a system through a unidirectional first clock line HSCL; transmitting and receiving first data with the system through a bidirectional first data line HSDA; transmitting the first clock signal to at least one target device through a unidirectional second clock line LSCL; transmitting and receiving second data with at least one target device through a bidirectional second data line LSDA; and determining, based on specific conditions, whether to transmit the first data to at least one target device or the second data to the system.
