Storage Media Based Search Function For Key Value Data Storage Devices

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller is configured to:
• generate one or more search buffers to search for a specific sequence of a value, wherein the specific sequence corresponds to a key value (KV) format in the memory device, wherein each of the one or more search buffers corresponds with a wordline of the memory device, and wherein the wordline of the memory device stores a plurality of values;
• send the generated one or more search buffers to the memory device, wherein the memory device is configured to:
• store the wordlines comprising the value of associated with the specific sequence in a latch of the memory device;
• and
• compare the wordlines comprising the value associated with the specific sequence with a corresponding search buffer of the one or more search buffers;
• and
• retrieve a portion of the value associated with the specific sequence with a corresponding search buffer of the one or more search buffers based on the comparing, wherein the portion matches the specific sequence.

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, wherein the controller is configured to:
• receive a search command from a host device for a specific sequence associated with a portion of a value of a key value (KV) pair data from the memory means, wherein the search command is associated with a KV format;
• generate a search buffer based on the received search command;
• retrieve one or more wordlines corresponding to the KV format from the memory device;
• compare the generated search buffer with the retrieved one or more wordlines;
• and
• provide at least a portion of the value from the retrieved one or more wordlines based on the comparing to the host device, wherein the at least a portion of the value matches the specific command.
