Abstract:
A data storage device implements a Zoned Namespace (ZNS) storage architecture. The data storage device delays the execution of write commands that are received out of sequence instead of rejecting the write commands. The write commands that are received out of sequence are reordered according to a logical block address (LBA) associated with each write command. The data storage device also checks for deadlock conditions that may arise due to the execution of the write commands being delayed and/or due to the write commands being reordered.
