US 2022/0091988 A1 · SYSTEM AND METHOD FOR SCALING COMMAND ORCHESTRATION THROUGH ADDRESS MAPPING

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.

Dependent claims

A device for processing commands to manage non-volatile memory, comprising:

a controller;
and
volatile memory,
wherein the controller is configured to:
obtain first address information from a first command;
read, based on the first address information, a first entry of a metadata table;
determine, based on the first entry of the metadata table, whether a first metadata page corresponding to the first address information is being processed by the controller;
in response to determining that the first metadata page corresponding to the first address information is being processed, determine a first processing status of the first metadata page, among a plurality of processing statuses, based on the first entry of the metadata table and process the first command according to the first processing status of the first metadata page;
and
in response to determining that the first metadata page corresponding to the first address information is not being processed, read the first metadata page from the non-volatile memory based on the first entry of the metadata table.

A method of processing commands to manage non-volatile memory, comprising:

obtaining, by a processor, first address information from a first command;
reading, by the processor based on the first address information, a first entry of a metadata table;
determining, by the processor based on the first entry of the metadata table, whether a first metadata page corresponding to the first address information is being processed by a controller;
in response to determining that the first metadata page corresponding to the first address information is being processed, determining by the processor a first processing status of the first metadata page, among a plurality of processing statuses, based on the first entry of the metadata table and process the first command according to the first processing status of the first metadata page;
and
in response to determining that the first metadata page corresponding to the first address information is not being processed, reading, by the processor, the first metadata page from the non-volatile memory based on the first entry of the metadata table.
