22.2.5.1 Automatic Page Program
(1)
Operation Description
The automatic page program writes data per page. When the program writes data to multiple pa-
ges, a page command need to be executed in page by page. Writing across pages is not possible.
Writing to Flash memory means that data cell of "1" becomes data of "0". It is not possible to be-
come data cell of "1" from data of "0". To become data cell of "1" from "0", the erase operation is re-
quired.
The automatic page program is allowed only once to each page already erased. Either data cell of
"1" or "0" cannot be written data twice or more. If rewriting to a page that has already been written
once, the automatic page program is needed to be set again after the automatic block erase or automat-
ic chip erase command is executed.
Note 1: Page program execution to the same page twice or more without erasing operation may dam-
age the device.
Note 2: Writing to the protected block is not possible.

How to Set
The 1st to 3rd bus write cycles indicate the automatic page program command.
In the 4th bus write cycle, the first address and data of the page are written. On and after 5th bus cy-
cle, one page data will be written sequentially. Data is written in one-word unit (32-bit).
If a part of the page is written, set "0xFFFFFFFF" as data, which means not required to write, for
entire one page.
No automatic verify operation is performed internally in the device. So, be sure to read the data pro-
grammed to confirm that it has been correctly written.
If the automatic page program is abnormally terminated, that page has been failed to write. It is rec-
ommended not to use the device or not to use the block including the failed address.
22.2.5.2 Automatic Chip Erase
(1)
Operation Description
The automatic chip erase is executed to the memory cell of all addresses. If protected blocks are con-
tained, these blocks will not be erased. If all blocks are protected, the automatic chip erase opera-
tion will not performed and will return to the read mode after a command sequence is input.
(2)
How to Set
The 1st to 6th bus write cycles indicate the automatic chip erase command. After the command se-
quence is input, the automatic chip erase operation starts.
No automatic verify operation is performed internally in the device. So, be sure to read the data
to confirm that it has been correctly erased.
