Abstract

Zoned memory typically requires write commands to be sent from a host to a data storage device in logical block address (LBA) sequential order. Instead of rejecting out-of-order write commands, the data storage device can execute those commands and internally deal with the out-of-order problem. For example, the data storage device can use a special zone logical-to-physical address table, use a temporary zone data buffer, and/or store a data's LBA in a header for later matching.
