An operating method of a storage device including a non-volatile memory is provided. The operating method includes: receiving a first source voltage through a first voltage signal pin; based on the first source voltage different from a target voltage of the storage device, controlling the first source voltage to the target voltage; receiving a command, which indicates an information request associated with an operation voltage of the storage device, from a host; transmitting a response, which corresponds to the information request, to the host by using the storage device; receiving a second source voltage which has a voltage level different from the first source voltage, through the first voltage signal pin; and providing the second source voltage to the non-volatile memory.

Operating method of storage device, operating method of host, and storage system including the storage device and the host

Disclosed is a user system which includes a first device and a second device, which share a shared voltage, and a power management integrated circuit (PMIC) generating the shared voltage. An operation method of the user system includes performing a first operation of the first device, determining whether a second operation of the second device is to be performed while the first device performs the first operation, based on an operation profile, and when it is determined that the second operation of the second device is to be performed while the first device performs the first operation, changing a power mode of the PMIC from a first power mode to a second power mode, before the second device performs the second operation. The PMIC generates the shared voltage based on the first power mode or the second power mode.

User system including first and second devices sharing shared voltage and power management integrated circuit generating shared voltage, and operation method thereof

A method of operating a host device includes transmitting a read command that requests information related to an eye open monitor (EOM) operation performed in a memory device to the memory device, and receiving a response signal including the information related to the EOM operation performed in the memory device from the memory device.
