DEVICE OPERATIONS
Pointer Operations
As the NAND Flash memories contain two differ-
ent areas for x16 devices and three different areas
for x8 devices (see
Figure 11.
) the read command
codes (00h, 01h, 50h) are used to act as pointers
to the different areas of the memory array (they se-
lect the most significant column address).
The Read A and Read B commands act as point-
ers to the main memory area. Their use depends
on the bus width of the device.
In x16 devices the Read A command (00h)
sets the pointer to Area A (the whole of the
main area) that is Words 0 to 255.
In x8 devices the Read A command (00h) sets
the pointer to Area A (the first half of the main
area) that is Bytes 0 to 255, and the Read B
command (01h) sets the pointer to Area B (the
■
■
second half of the main area) that is Bytes 256
to 511.
In both the x8 and x16 devices the Read C com-
mand (50h), acts as a pointer to Area C (the spare
memory area) that is Bytes 512 to 527 or Words
256 to 263.
Once the Read A and Read C commands have
been issued the pointer remains in the respective
areas until another pointer code is issued. Howev-
er, 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 pro-
gram command 80h is issued (see
Figure 12.
).
