hi all, thank you for this information, now I know why I bought Flash memory cheaper than EEPROM. tung > > They are almost same thing with little difference. > 1. Flash you can write each bite separately but if you want to erace > same bite you have to erace hole array like block. > 2. EEPROM is more flexible you can rewrite individual bite without > erasing hole array. > Function of Flash is similar to your camera flash that is why the name > is flash. > 3. flash is cheaper then eeprom that is why MICROCHIP is moving to Flash > technology. > 4. What I do not like about flash programming them slower then OTP. > > Andre > > > > > > > > ========================================== > = http://www.compufire.com = > = mailto:andre@compufire.com = > = mailto:mcu-engineering@compufire.com = > = Andre Abelian: Engine Electronics, Inc.= > = Tel 909-589-5485 Fax 909-598-5695 = > ========================================== >
