1Gbit (128Mx8bit / 64Mx16bit) NAND Flash
Once the Read A and Read C commands have been issued the pointer remains in the respective areas until another
pointer code is issued. However, the Read B command is effective for only one operation, once an operation has been
executed in Area B the pointer returns automatically to Area A.
The pointer operations can also be used before a program operation, that is the appropriate code (00h, 01h or 50h)
can be issued before the program command 80h is issued (see Figure 9).
