A link startup method of a storage device connected to a host through a plurality of lanes includes performing an initialization operation in the storage device; establishing data communication through a connected transmission lane and a connected reception lane among the plurality of lanes; transmitting a high speed link up message to the host through the connected transmission lane of the storage device; and performing a link startup operation in a high speed mode through the connected transmission lane of the storage device and the connected reception lane of the host, based on the high speed link up message transmitted by the storage device.

Storage device for high speed link startup and storage system including the same

An image sensor includes: a first device isolation part in a substrate and defining an active region; a first gate electrode having a first and second gate sidewalls; and a first impurity region and a second impurity region adjacent to the first and second gate sidewalls, wherein the active region includes: a first active central part; a first active protrusion; and a second active protrusion, wherein the first device isolation part has a first isolation sidewall overlapping the first active central part, and wherein a first straight line is at least partially spaced apart from the first isolation sidewall, wherein the first straight line links a first point, at which the first active protrusion meets the first active central part, to a second point, at which the second active protrusion meets the first active central part.

Image sensor and semiconductor device including asymmetric active region

A host controller interface configured to provide interfacing between a host device and a storage device includes processing circuitry; a doorbell register configured to store a head pointer and a tail pointer of one or more first queues; and an entry buffer configured to store a first command from one of the one or more first queues in the entry buffer, wherein the processing circuitry is configured to, determine an order in which the commands of the one or more first queues are to be processed, route the first command to be stored in the entry buffer according to the determined order, and route a first response to be stored in one of one or more second queues.

Host controller interface using multiple circular queue, and operating method thereof

Provided are a storage device configured to perform high-speed link startup and a storage system including the storage device. The storage system performs data communication through a connected transmission lane and a connected reception lane from among a plurality of lanes between a host and the storage device. The host transmits an activate period of the connected transmission lane, which is less than a first time period, to the connected reception lane, and the storage device receives the activate period of the connected reception lane, which is less than the first time period. The host and the storage device perform link startup in a high-speed mode through the connected transmission lane and the connected reception lane, based on the activate period being less than the first time period.

Storage device for performing high-speed link startup and storage system including the same

An electronic device may include a host device and a storage device which are connected in a universal flash storage standard, wherein the host device may include processing circuitry configured to process a submission queue (SQ) and a completion queue (CQ), wherein the SQ is a processing standby line of a command, and the CQ is a processing standby line of a response received from the storage device, transmit the command to the storage device, store a host command credit in a host command register, the host command credit indicating an estimated command accommodation limit of the storage device, store the response in a response slot, and store a host response credit in a host command register, the host command credit indicating a limit of the response slot.
