STORAGE DEVICE AND METHOD FOR RESTORING META DATA THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 17973184 titled 'STORAGE DEVICE AND METHOD FOR RESTORING META DATA THEREOF

Simplified Explanation

The abstract describes an operating method for a storage device that involves loading journal data from a non-volatile memory device and restoring corresponding meta data to a storage controller based on a cache allocation flag. The cache allocation flag determines whether the meta data should be allocated to a meta cache or stored in a meta buffer.

  • The method involves loading journal data from a non-volatile memory device.
  • A cache allocation flag included in the journal data is identified.
  • Meta data corresponding to the journal data is restored to a storage controller based on the cache allocation flag.
  • The cache allocation flag can be a first flag indicating that the meta data should be allocated to a meta cache of the storage controller.
  • Alternatively, the cache allocation flag can be a second flag indicating that the meta data should be stored in a meta buffer of the storage controller.

Potential Applications

  • This operating method can be applied in various storage devices such as hard drives, solid-state drives, or network-attached storage systems.
  • It can be used in systems that require efficient management of meta data for improved storage performance.

Problems Solved

  • The method solves the problem of efficiently restoring meta data to a storage controller from journal data.
  • It addresses the challenge of determining whether the meta data should be allocated to a meta cache or stored in a meta buffer.

Benefits

  • By using the cache allocation flag, the method optimizes the allocation of meta data, leading to improved storage performance.
  • It allows for faster restoration of meta data to the storage controller, enhancing overall system efficiency.
  • The method provides flexibility in managing meta data based on the specific requirements of the storage device or system.


Original Abstract Submitted

An operating method of a storage device, the method including; loading journal data from a non-volatile memory device, identifying a cache allocation flag included in the journal data, and restoring meta data corresponding to the journal data to a storage controller in response to the cache allocation flag. Here, the cache allocation flag is a first flag when the meta data are allocated to a meta cache of the storage controller, and the cache allocation flag is a second flag when the meta data are stored to a meta buffer of the storage controller.
