    hi all,
    i have gone through some of the questinos regarding miniSD, SD and MMC
    on net. here is my set of questions:
    1. what is terminal guard?( usually mentioned as a difference between
    miniSD and SD)
    2. does miniSD have write protection switch?
    3. if no(to question 2), why is it called 'miniSD'. it should have been
    called a 'miniMMC'(beacuse of write protect switch)
    4. does miniSD have copyright protection?
    5. does SD,miniSD and MMC have XIP(execute in place) capability?
    6. what is the access method of these flashes?(sequential or random)

    thank you,
