Storage device supporting multiple communication types and operating method thereof

Abstract

A storage device includes nonvolatile memory devices, a connector that includes connection terminals, and a controller that communicates with an external host device through the connector and to control the nonvolatile memory devices. The connector provides the external host device with detection information in response to the connector being connected with the external host device. Power is supplied from the external host device to the controller and the nonvolatile memory devices through the connector in response to the providing of the detection information. The connector provides the external host device with information of a communication type in which the controller communicates with the external host device, after the power is supplied. The communication type is one of a first communication type and a second communication type. The controller configures the connection terminals to correspond to a single or dual port based on a signal received from the external host device.
