在深入了解Flash存儲(chǔ)器的基礎(chǔ)上，采用單片機(jī)自動(dòng)檢測(cè)存儲(chǔ)器無(wú)效塊。主要通過(guò)讀取每一塊的第1、第2頁(yè)內(nèi)容，判斷該塊的好壞，并給出具體的實(shí)現(xiàn)過(guò)程，以及部分關(guān)鍵的電路原理圖和C語(yǔ)言程序代碼。該設(shè)計(jì)最終實(shí)現(xiàn)單片機(jī)自動(dòng)檢測(cè)Flash壞塊的功能，并通過(guò)讀取ID號(hào)檢測(cè)Flash的性能，同時(shí)該設(shè)計(jì)能夠存儲(chǔ)和讀取1GB數(shù)據(jù)。
Abstract:
On the basis of in-depth understanding the Flash chips，this paper designs a new program which using the SCM to detect the invalid block.Mainly through reading the data of the first and second page to detect the invalid block.Specific implementation procedure was given,and the key circuit schematic diagram and C language program code was introduced.This design achieved the function of using the MCU checks the invalid block finally，and increased the function by reading the ID number of Flash to get the performance of the memory.And the design also can write and read1GB data
