DATA WRITING METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18147362 titled 'DATA WRITING METHOD AND APPARATUS

Simplified Explanation

The patent application describes a data writing method and computing devices used in a computer system with a file system and flash memory-based storage system. The method involves obtaining a target logical address, which is an address allocated to the target data in the flash memory-based storage system. The target logical address belongs to a specific logical block in the file system. The target data is then written into a corresponding physical block in the flash memory-based storage system.

  • The method involves obtaining a target logical address for data to be written into a flash memory-based storage system.
  • The target logical address is allocated from a specific logical block in the file system.
  • The flash memory-based storage system consists of multiple physical blocks.
  • The method determines that the target logical address belongs to the specific logical block.
  • The target data is written into a corresponding physical block based on the correspondence between the logical block and physical block.

Potential Applications

  • This technology can be applied in computer systems with flash memory-based storage systems, such as smartphones, tablets, and solid-state drives (SSDs).
  • It can be used in file systems that require efficient data writing methods for flash memory-based storage.

Problems Solved

  • The method solves the problem of efficiently writing data into a flash memory-based storage system.
  • It addresses the challenge of managing logical and physical blocks in the file system and flash memory-based storage system.

Benefits

  • The method allows for efficient data writing by allocating target logical addresses and mapping them to physical blocks.
  • It improves the performance and reliability of flash memory-based storage systems.
  • The method simplifies the management of logical and physical blocks in the file system.


Original Abstract Submitted

Data writing methods and computing devices are provided. An example data writing method is applied to a computer system, and the computer system includes a file system and a flash memory-based storage system. The example data writing method includes obtaining a target logical address, where the target logical address is an address allocated from a first logical block to target data to be written into the flash memory-based storage system, the first logical block is one of multiple logical blocks in the file system, and the flash memory-based storage system includes multiple physical blocks. It is determined that the target logical address belongs to the first logical block. The target data is written into a first physical block based on a correspondence between the first logical block and the first physical block, where the first physical block is one of the multiple physical blocks.
