Storage device, operating method of storage device, and storage system where failure signal is generated based on logical address mismatch

An operating method of a storage device, comprising:

• receiving an operation request for writing write data to a position corresponding to a first logical block address in a plurality of zones, the plurality of zones configured to sequentially store data based on a write pointer indicating a position to write the data;
• determining, based on the first logical block address, i) a target zone to write among the plurality of zones and ii) a target write pointer indicating a position to write in the target zone, and determining whether to process the operation request based on a position of a current write pointer of the target zone and the position of the target write pointer;
• storing the write data as preliminary data in a second memory based on determining that the operation request cannot be processed;
• generating a failure signal indicating that the operation request cannot be processed based on the first logical block address corresponding to the operation request in response to determining that the operation request cannot be processed;
• receiving a sync command including the first logical block address;
• and
• reading the preliminary data and writing the preliminary data to the position corresponding to the current write pointer of the target zone.

An operating method of a storage device, the storage device including a first memory and a second memory, the method comprising:

• receiving, by the storage device, a plurality of operation requests from a host device, each of the plurality of operation requests including a logical block address, a write command, and write data;
• determining, by the storage device, whether a first operation request of the plurality of operation requests is processable, based on a comparison between a first logical block address corresponding to the first operation request and a write pointer of the first memory, wherein the first memory includes a plurality of zones configured to sequentially store data based on the write pointer, the write pointer indicating a position to write the data;
• storing, by the storage device, first write data corresponding to the first operation request in the second memory as first preliminary data, based on a determination that the first operation request cannot be processed;
• transmitting, by the storage device to the host device, a failure signal indicating that the first operation request cannot be processed, the failure signal being generated based on the first logical block address corresponding to the first operation request;
• and
• receiving, by the storage device, a sync command from the host device.
