STORAGE DEVICE, OPERATING METHOD OF STORAGE DEVICE, AND STORAGE SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17973071 titled 'STORAGE DEVICE, OPERATING METHOD OF STORAGE DEVICE, AND STORAGE SYSTEM
Simplified Explanation
The patent application describes a storage device that includes a nonvolatile memory and a controller. The controller is designed to manage a hot list and a hot hash table to efficiently store and retrieve data.
- The storage device includes a nonvolatile memory and a controller.
- The controller inserts a portion of a logical address into a hot list.
- The controller manages a hot hash table that stores the position of the logical address in the hot list.
- The controller can search the hot hash table using the logical address to find the position in the hot list.
- The controller determines an attribute of the data corresponding to the logical address based on the search result.
- The controller stores attribute information indicating the attribute of the data.
Potential Applications
- This technology can be applied in various storage devices such as solid-state drives (SSDs) or flash memory devices.
- It can improve the efficiency and performance of data storage and retrieval in these devices.
Problems Solved
- Traditional storage devices may experience performance issues when storing and retrieving data.
- The patent addresses the problem of efficiently managing data storage and retrieval in a storage device.
Benefits
- The use of a hot list and hot hash table allows for faster and more efficient data storage and retrieval.
- By storing attribute information, the storage device can quickly determine the attribute of the data without extensive searching.
- This technology can improve the overall performance and responsiveness of storage devices.
Original Abstract Submitted
A storage device includes a nonvolatile memory and a controller. The controller is configured to insert, into a hot list, a portion of a logical address received from a host and manage a hot hash table storing a position, at which the logical address is inserted into the hot list. The controller is further configured to search the hot hash table for the position, at which the logical address is inserted into the hot list, by using the logical address, determine an attribute of data corresponding to the logical address based on the search result, and store attribute information indicating the attribute of the data.
