Pointer Operation of K9F1208X0A(X8)
Samsung NAND Flash has three address pointer commands as a substitute for the two most significant column addresses. ’ 00h’
command sets the pointer to ’ A’ area(0~255byte), ’ 01h’ command sets the pointer to ’ B’ area(256~511byte), and ’ 50h’ command sets
the pointer to ’ C’ area(512~527byte). With these commands, the starting column address can be set to any of a whole
page(0~527byte). ’ 00h’ or ’ 50h’ is sustained until another address pointer command is inputted. ’ 01h’ command, however, is effec-
tive only for one operation. After any operation of Read, Program, Erase, Reset, Power_Up is executed once with ’ 01h’ command,
the address pointer returns to ’ A’ area by itself. To program data starting from ’ A’ or ’ C’ area, ’ 00h’ or ’ 50h’ command must be input-
ted before ’ 80h’ command is written. A complete read operation prior to ’ 80h’ command is not necessary. To program data starting
from ’ B’ area, ’ 01h’ command must be inputted right before ’ 80h’ command is written.
