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.

Storage system with capacity scalability and method of operating the same

An event notification method of a storage device includes detecting an event in the storage device, writing an asynchronous event information entry corresponding to the event in a completion queue of a host, and transmitting an interrupt corresponding to a transmission of the asynchronous event information entry to the host. The asynchronous event information entry is provided to the host regardless of reception of an asynchronous event request command from the host.

A fuel cell system with reduced volume through decreasing the thickness of a stack comprises: a stack which comprises a plurality of membrane electrode assemblies stacked so that the cathode electrodes face each other and the anode electrodes face each other, and separators that are interposed between the membrane electrode assemblies, and which have a flow path passing through from a first face to a second face on a region corresponding to a region where each cathode electrode or anode electrode is formed.
