Jump page cache read method in NAND flash memory and NAND flash memory

摘要

A NAND flash memory including a control unit which includes a signal receiving circuit and a flash array; the signal receiving circuit is used to receive a cache read command from an external NAND controller; the flash array includes at least one chip, each chip includes at least one plane, each plane includes a plurality of blocks, each block includes a plurality of pages; when a cache read command is received, it reads pages in a first block according to an address of the page until reaching the last page in the first block; when the last page in the first block is reached, an address of a next to-be-read page is generated according to an address of the last page in the first block to allow the cache read command to read the next to-be-read page.
