Storage Media Based Search Function For Key Value Data Storage Devices - A simplified explanation of the abstract

This abstract first appeared for US patent application 17850352 titled 'Storage Media Based Search Function For Key Value Data Storage Devices

Simplified Explanation

The abstract describes a data storage device that includes a memory device and a controller. The controller receives a search command from a host device for a specific value associated with a key value (KV) format. It prepares search buffers and sends them to the memory device. The controller retrieves wordlines containing KV pair data and compares them with the search buffers to find values with the specific sequence. It then provides at least a portion of the value from the KV pair data to the host device.

  • The data storage device includes a memory device and a controller.
  • The controller receives a search command from a host device for a specific value associated with a key value (KV) format.
  • The controller prepares search buffers and sends them to the memory device.
  • The controller retrieves wordlines containing KV pair data.
  • The retrieved wordlines are compared with the search buffers to find values with the specific sequence.
  • At least a portion of the value from the KV pair data is provided to the host device based on the comparison.

Potential Applications

  • This technology can be applied in various data storage devices such as solid-state drives (SSDs) or databases.
  • It can be used in systems that require efficient searching and retrieval of specific values associated with a key value format.

Problems Solved

  • The technology solves the problem of efficiently searching for specific values in a key value format within a data storage device.
  • It eliminates the need for the host device to perform complex search operations, offloading the workload to the data storage device.

Benefits

  • The data storage device provides faster and more efficient searching and retrieval of specific values.
  • It reduces the processing burden on the host device, improving overall system performance.
  • The technology enables quicker access to data, enhancing the user experience and productivity.


Original Abstract Submitted

A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to receive a search command from a host device, where the search command is for value associated with a key value (KV) format having a specific sequence, prepare one or more search buffers and send the one or more search buffers to the memory device, retrieve one or more wordlines having KV pair data associated with the KV format, where the KV pair data includes a key and a value, compare the retrieved one or more wordlines with the one or more search buffers for values having the specific sequence, and provide at least a portion of the value from one or more KV pair data based on the comparing to the host device.
