A storage device and an operating method thereof are provided. The storage device includes a non-volatile memory and a storage controller. The storage controller includes a command and address generator, an error detection module, and an interface circuit. The command and address generator generates a first command, an address, and a second command, the second command including an error detection signal for detecting a communication error in the first command and the address. The error detection module generates the error detection signal from the first command and the address. The interface circuit sequentially transmits the first command, the address, and the second command to the non-volatile memory. The first command indicates a type of a memory operation to be performed in the non-volatile memory, and the second command corresponds to a confirm command.

Storage device and operating method of storage controller

The present disclosure provides a storage system including a first storage device (e.g., a main storage device) and one or more additional storage devices (e.g., sub storage devices). The first storage device includes a host interface for communicating with a host device and is directly connected to the host device. The additional storage devices may be directly connected to the first storage device and may communicate with the host device through the host interface included in the first storage device. The storage system thus has a total combined capacity of both the capacity of the first storage device and the capacity of the one or more additional storage devices. Further, the one or more additional storage devices may be added or removed to increase or decrease the total capacity of the storage system, and the one or more additional storage devices may not necessarily themselves include a host interface.
