Alignment optimization of key value pair data storage

A data storage device, comprising:

• a memory device;
• and
• a controller coupled to the memory device, wherein the controller is configured to:
• receive a read command to read key value (KV) pair data, wherein the KV pair data includes a key and a value;
• determine if an aggregate wordline exists in the data storage device, wherein the aggregate wordline stores residual data of one or more KV pair data that exceeds a size of a wordline, and wherein the aggregate wordline includes residual data corresponding to the KV pair data;
• determine that the aggregate wordline exists in a first memory location of the memory device;
• read the KV pair data from a second memory location of the memory device based on the determining, wherein the first memory location and the second memory location are different memory types;
• and
• provide the residual data corresponding to the KV pair data from the first memory location and the KV pair data from the second memory location.

A data storage device, comprising:

• memory means;
• and
• a controller coupled to the memory means, wherein the controller comprises an analysis and aggregation module, wherein the analysis and aggregation module is configured to:
• determine a length of a received key value (KV) pair data, wherein the length is greater than a size of a target wordline for programming of the received KV pair data;
• and
• determine a maximum number of values to store in an aggregate wordline, wherein the aggregate wordline stores residual data of one or more KV pair data, and wherein the residual data corresponds to data of the one or more KV pair data that exceeds the size of the target wordline;
• and
• wherein the controller is configured to:
• aggregate the residual data of the one or more KV pair data to the aggregate wordline;
• and
• program the aggregate wordline to the memory means.
