2.2K9F2808U0C讀寫操作

K9F2808U0C共有1024塊，每塊32頁(yè)，每頁(yè)528B，其中512B用于存放數(shù)據(jù)，另外16B用于存放信息，如塊的好壞標(biāo)記、塊邏輯地址和ECC校驗(yàn)和等。FLASH讀寫有其自身的特點(diǎn)，讀寫都以頁(yè)為單位，可以隨機(jī)讀，但無(wú)法隨機(jī)寫，寫操作前必須把寫單元所在的塊擦除。因此，對(duì)于該閃存的讀操作可以采取直接讀取來(lái)處理；而對(duì)于寫操作，則通過(guò)設(shè)置塊緩沖來(lái)解決，以減輕系統(tǒng)的任務(wù)和對(duì)FLASH的擦除次數(shù)。寫操作的基本思想是：設(shè)置一個(gè)塊緩沖區(qū)，待寫數(shù)據(jù)先寫入緩沖區(qū)對(duì)應(yīng)的頁(yè)地址，當(dāng)緩沖區(qū)中待寫數(shù)據(jù)的頁(yè)地址到達(dá)31或者頁(yè)地址未滿31但傳輸已經(jīng)結(jié)束時(shí)，先將目標(biāo)塊中待寫頁(yè)以外的有關(guān)數(shù)據(jù)保存到緩沖區(qū)對(duì)應(yīng)的頁(yè)地址，然后擦除整塊，最后將緩沖區(qū)的數(shù)據(jù)拷貝到該塊。
