[DocumentsNAND FLASH 存取原理

Description: NAND Flash 的數據是以bit 的方式保存在memory cell,一般來說,一個cell 中只能存儲一個bit。這些cell 以8 個或者16 個為單位,連成bit line,形成所謂的byte(x8)/word(x16),這就是NAND Device 的位寬。這些Line 會再組成Page. (Nand Flash 有多種結構,我使用的Nand Flash 是K9F1208,下面內容針對三星的K9F1208U0M),每頁528Byte,每32 個page 形成一個Block, Sizeof(block)=16kByte 。
