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.
Table 3. Destination of the pointer
(1) Command input sequence for programming ’ A’ area
(2) Command input sequence for programming ’ B’ area
Command
00h
50h
’ A’ ,’ B’ area can be programmed.
It depends on how many data are inputted.
