Pointer Operation of K9F5616X0C(X16)
Samsung NAND Flash has two address pointer commands as a substitute for the most significant column address. ’00h’ command
sets the pointer to ’A’ area(0~255word), and ’50h’ command sets the pointer to ’B’ area(256~263word). With these commands, the
starting column address can be set to any of a whole page(0~263word). ’00h’ or ’50h’ is sustained until another address pointer com-
mand is inputted. To program data starting from ’A’ or ’B’ area, ’00h’ or ’50h’ command must be inputted before ’80h’ command is
written. A complete read operation prior to ’80h’ command is not necessary.
