Embodiment

[0033] figure 1 A structural block diagram of a Nand flash element provided by an embodiment of the present invention.

[0034] refer to figure 1 As shown, the Nand flash component provided in this embodiment includes a package body 10 , and a Nand flash core 11 and an internal controller 12 are arranged in the package body. The Nand flash core includes multiple Blocks, each Block is composed of multiple Pages, and each Page is composed of multiple Celllines, and the core also includes a storage area for storing ECC check codes.

[0035] The above-mentioned internal controller is used to control the Nand flash core, and the internal controller specifically includes a basic configuration module 121 , a basic loading module 122 , a low-level format module 123 and a product firmware module 124 .

[0036] Among them, the above-mentioned basic configuration module is used to store the basic information and configuration information of the Nand flash core, such as page size, block...

Abstract

The invention provides a Nand flash component and its communication control method and device. The Nand flash component specifically includes a package body, the package body is packaged with a Nand flash core and an internal controller, and the internal controller includes a basic configuration module and a basic loading module , low-level module and product firmware module. And specifically through the product firmware module to implement ECC check management, bad block management, address mapping management or loss leveling management on the Nand flash core, so that there is no need to implement the above management through the off-chip main controller, thus effectively solving the problem of A problem with a heavy burden on the main controller.

Description

technical field [0001] The invention relates to the technical field of memory, in particular to a Nand flash element. Background technique [0002] Nand flash is a kind of flash memory, which uses nonlinear macro-cell mode inside, which provides a cheap and effective solution for the realization of solid-state large-capacity memory. Nand flash has the advantages of large capacity and fast rewriting speed. It is suitable for the storage of large amounts of data, so it has been more and more widely used in the industry. For example, embedded products include digital cameras, MP3 walkman memory cards, small and exquisite U disk, etc. [0003] The data of Nand flash is stored in the memory cell in the form of bits. Generally speaking, only one bit can be stored in each cell; these cells are connected into bit lines in units of 8 or 16 to form a so-called byte ( x8) / word(x16), this is the bit width of NAND Device. These bit lines form a page, and the number of bit lines per pa...
