A brief review of newly available features of Flash Doctor v1.40:
1. Add the feature to modify page size.
For some FLASH device, the program can not correctly detect the real page size; therefore the program provides an option for users to modify page size after analysis. Example, if the program detects the page size as 4224, but users find that data is not complete in a page, namely there is not enough bytes to form a sector. In this case, users can modify the page size and read the chip again.
Procedure for modifying page size:
Step 1. Input added bytes in the blank marked in red as above. Example, if users think that real page size should be 4288, you need to input 64.
Step 2. Click the button of Chip Identification.
Step 3. Read the data from chip once more.
2. Special Page Structure
Generally, data unit in FLASH device are composed of 512 bytes data plus some bytes of service word, i.e. 512+16. However, some FLASH devices have special page structure. The standard data unit is divided into several sections, namely sub data unit is less than 512 bytes. Another special structure is that several data unit will merge into bigger unit, namely the data unit is bigger than 512 bytes.
3. Block is divided into sections
As in the above picture, the data unit has 528 bytes, which is divided into three sections:
Data Unit Size=SectionSize1+SectionSize2+SectionSize3
528=512+16=(176+4)+(168+4)+(168+8)
4. Sections merge into bigger block
As in the above picture, four data units will merge into the data unit:
Data Unit Size=SectionSize1+SectionSize2+SectionSize3+SectionSize4
4288=(1024+50)+(1024+46)+(1024+46)+(1024+50)
5. Half Page
For some FLASH device, data will not be stored in a whole page. Instead, only the first half will be used and the second half will be filled with “FFFF”. Users need to select the option of Half Page, thus the program can correctly collect the data.
