  • Flash memory management method
    Patent number: 6938116
    Abstract: A flash memory management method is provided. According to the method, when a request to write the predetermined data to a page to which data has been written is made, the predetermined data is written to a log block corresponding to a data block containing the page. When a request to write the predetermined data to the page again is received, the predetermined data is written to an empty free page in the log block. Even if the same page is requested to be continuously written to, the management method allows this to be processed in one log block, thereby improving the effectiveness in the use of flash memory resources.

  • Method of driving remapping in flash memory and flash memory architecture suitable therefor
    Patent number: 6381176
    Abstract: A method of driving remapping in a flash memory, which is capable of writing the status of a block and a unit by reducing the number of partial write cycles as much as possible, and a flash memory architecture adapted thereto are provided. The remapping driving method includes searching for a predetermined physical unit based on mapping information about a predetermined block, searching the found physical unit for another block, the status of which is free, if the predetermined block exists in a valid state in the physical unit; changing the status of the other block into a status next to the status of the predetermined block, writing new data and additional information such as a logical block number to the other block, and changing the status of the predetermined block to a deleted state. Accordingly, the write status of a block or a unit can be managed for a flash memory having a restriction on the number of partial write cycles.
