Abstract
A device for processing commands to manage non-volatile memory includes a controller configured to obtain address information from a command, read, based on the address information, an entry of a metadata table, and determine, based on the entry of the metadata table, whether a metadata page corresponding to the address information is being processed by the controller. In response to determining that the metadata page corresponding to the address information is being processed, the controller determines a processing status of the metadata page, among a plurality of processing statuses, based on the entry of the metadata table and processes the command according to the processing status of the first metadata page. In response to determining that the metadata page corresponding to first address information is not being processed, the controller reads the metadata page from the non-volatile memory based on the entry of the metadata table.
