Table 86.
For NAND Flash memory, the common and attribute memory spaces are subdivided into
three sections (see in
●
●
●
Table 87.
The application software uses the 3 sections to access the NAND Flash memory:
●

●
Since the NAND Flash memory automatically increments addresses, there is no need to
increment the address of the data section to access consecutive memory locations.

Data section (first 64 Kbytes in the common/attribute memory space)
Command section (second 64 Kbytes in the common / attribute memory space)
Address section (next 128 Kbytes in the common / attribute memory space)
To send a command to NAND Flash memory: the software must write the command
value to any memory location in the command section.
To specify the NAND Flash address that must be read or written: the software must
write the address value to any memory location in the address section. Since an
address can be 4 or 5 bytes long (depending on the actual memory size), several
consecutive writes to the address section are needed to specify the full address.
To read or write data: the software reads or writes the data value from or to any
memory location in the data section.
