CONTROLLER, FLASH MEMORY APPARATUS, AND METHOD FOR WRITING DATA INTO FLASH MEMORY APPARATUS

摘要

A storage controller for determining an amount of data to be sent to a flash memory apparatus for storage comprises a communications interface for communicating with the flash memory apparatus and a processor. The flash memory apparatus comprises a block including a plurality of pages. And at least one of the pages is unavailable for storage. The processor is configured to receive information of the block sent by the flash memory apparatus, wherein the information includes capacity of one or more unavailable pages in the block. And then, the processor determines an available capacity of the block, based on the information and a total capacity of the block. Further, the processor obtains data to be sent to the flash memory apparatus, wherein an amount of the data is equal to the available capacity of the block. At last, the processor sends the data to the flash memory apparatus.
