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
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 inp
before ’80h’command is written. A complete read operation prior to ’80h’command is not necessary. To program data starting fro
’B’area, ’01h’command must be inputted right before ’80h’command is written.

’B’ ’C’area can be programmed.
It depends on how many data are inputted.
’01h’command must be rewritten before
every program operation
The address pointer is set to ’B’area(256~512), and will be reset to
’A’area after every program operation is executed.
