METHOD OF OPERATING A STORAGE DEVICE USING MULTI-LEVEL ADDRESS TRANSLATION AND A STORAGE DEVICE PERFORMING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17945256 titled 'METHOD OF OPERATING A STORAGE DEVICE USING MULTI-LEVEL ADDRESS TRANSLATION AND A STORAGE DEVICE PERFORMING THE SAME

Simplified Explanation

The abstract describes a method of operating a storage device with a nonvolatile memory. Here is a simplified explanation of the abstract:

  • The method involves generating virtual domains, each containing page mapping and block mapping tables.
  • When a data input/output (I/O) request is received, the method performs a data I/O operation using the virtual domains.
  • A data I/O response is then transmitted to a host device in response to the data I/O request and operation.
  • The virtual domains can be changed based on a direct request from the host device or a change in a first parameter associated with the data I/O request.
  • If the first parameter changes, a second parameter associated with the data I/O response is also changed by modifying the virtual domains and performing the data I/O operation using the changed virtual domain.

Potential applications of this technology:

  • This method 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 input/output operations in these storage devices.

Problems solved by this technology:

  • The method addresses the need for efficient data input/output operations in storage devices.
  • It allows for dynamic changes in virtual domains based on host device requests or changes in parameters, optimizing the storage device's performance.

Benefits of this technology:

  • By using virtual domains, the method enables efficient data management and organization within the storage device.
  • The ability to change virtual domains based on host device requests or parameter changes allows for improved performance and adaptability.
  • The method enhances the overall efficiency and responsiveness of the storage device.


Original Abstract Submitted

A method of operating a storage device including a nonvolatile memory, the method including: generating virtual domains each of which including page mapping and block mapping tables; receiving a data input/output (I/O) request; performing a data I/O operation corresponding to the data I/O request using the virtual domains; transmitting a data I/O response to a host device in response to the data I/O request and the data I/O operation; and changing at least one of the virtual domains based on a direct request from the host device or a change in a first parameter associated with the data I/O request, and wherein, in response to the first parameter being changed, a second parameter associated with the data I/O response is changed by changing at least one of the virtual domains and by performing the data I/O operation using the changed virtual domain.
