Unique ID for Copyright Protection；
在datasheet里面有上面这个话，我们想用作硬件id码用。不知道那位知道。 上网找半天也没有什么资料！
toshiba有下面的一段话
Product Features
-- A unique, permanent identification number is stored on each memory chip.
-- The identification number is recorded on the NAND as one-time programmable data that is tamper proof, and cannot be rewritten or altered after shipment.
-- The identification number is recorded on a 128-bit basis, bit expansion is also provided.
-- A special command, not in the public domain, is necessary to read the number.
-- Development of a copyright protection system requires an architecture that supports the entire system, including use of an encryption key in combination with the ID number.
Copyright Protection Information
Progress in semiconductor technology, modem performance and other areas has reached a point where downloading CD-quality music from Web sites is set to become a high-growth market. Achieving the full potential of Internet delivery requires copyright protection, which Toshiba is supporting with the new copyright protection identification number feature on its NAND Flash EEPROMs.
Toshiba's NAND Flash memory solutions are quickly becoming the file-storage device of choice for the digital age. Current applications range from digital cameras to semiconductor disks, while NANDs versatility and cost-performance position makes it the ideal memory for electronic books and digital music players (MP3). Toshiba continues to develop NAND to meet the high data capacities required by these emerging applications.
这个id应该是在出厂的时候就有了的，而且是写在一次性编程的块里面，不能再次写了。 要用special command 才能读出来， |
