Data Storage Device and Method for Storage-Class-Memory-Accelerated Boot Partition Optimization - A simplified explanation of the abstract

This abstract first appeared for US patent application 17752264 titled 'Data Storage Device and Method for Storage-Class-Memory-Accelerated Boot Partition Optimization

Simplified Explanation

The patent application describes a data storage device with two memory units and a controller.

  • The first memory has faster access time than the second memory.
  • The controller stores a code called host-initialization code in the first memory.
  • A copy of the host-initialization code is also stored in the second memory.
  • The controller determines that the copy of the code in the second memory should be designated as the main version.
  • The controller then relocates the copy of the code to the first memory, making it the main version.
  • This main version of the code is accessed to boot-up the host.
  • The patent application mentions that there can be other embodiments and combinations of these features.


Original Abstract Submitted

A data storage device comprises a first memory, a second memory, and a controller. The first memory has a faster access time than the second memory. The controller is configured to store host-initialization code in the first memory, store a copy of the host-initialization code in the second memory, determine that the copy of the host-initialization code should be designated as the main version of the host-initialization code, and relocate the copy of the host-initialization code to the first memory, which makes the copy of the host-initialization code the main version of the host-initialization code that is accessed to boot-up the host. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
