Abstract
A method of operating a controller for controlling the programming of a NAND memory chip is shown. The NAND memory chip has a plurality of blocks with each block having a certain amount of storage, wherein the amount of storage in each block is the minimum erasable unit. The method comprising storing in a temporary storage a first plurality of groups of data, wherein each of the groups of data is to be stored in a block of the NAND memory chip. Each group of data is indexed to the block with which it is to be stored. Finally, the groups of data associated with the same block are programmed into the same block in the same programming operation.
