说明：  介绍了高密度K9K8G08U0M NAND flash芯片的内部组成、引脚配置、各种读操作、页面编程、块擦除、写保护等操作时序和状 态查询。提供了NAND flash存储器与其宿主控制器的标准接口逻辑。
(The paper introduces the internal logicalarchitecture, external pins configuration and functions,the page read operations,the page programoperations,the block erase operations,the write protection and command sequences and status polling of K9K8G08U0Mhighdensity NAND flash chip. It also provides the NAND flash chips tostandard interface with the flash host controller.)
