How to write using a log-based buffering of the NAND memory to block-based file system

摘要

Method of operating a controller for controlling the programming of the NAND memory chips is illustrated. Has a plurality of blocks, one block and one is a one having a storage amount of a particular, NAND memory chip is the smallest erasable unit of the amount of storage in each block. The method, one by one but has the stage to be stored in the temporary storage of the data group that is to be stored in a block of the NAND memory chip, the data groups of the first. Data groups each of which is indexed for the block when it comes to be stored. Finally, the data groups that are associated with the same block are programmed to the same block in the same programming operation. [Selection Figure Figure 3
