(4) Commands
1) Automatic Page Programming
Writing to a flash memory device is to make "1" data cells to "0" data cells. Any "0" data cell
cannot be changed to a "1" data cell. For making "0" data cells to "1" data cells, it is
necessary to perform an erase operation.
The automatic page programming function of this device writes data of each page. The
TMPM370FY contains 64 words in a page. A 64 word block is defined by a same [31:8]
address and it starts from the address [7:0] = 0 and ends at the address [7:0] = 0xFF. This
programming unit is hereafter referred to as a "page."
control by the CPU is required. The state of automatic page programming (whether it is in
writing operation or not) can be checked by the FCFLCS [0] <RDY/BSY> register.
Also, any new command sequence is not accepted while it is in the automatic page
programming mode. If it is desired to interrupt the automatic page programming, use the
hardware reset function. If the operation is stopped by a hardware reset operation, it is
necessary to once erase the page and then perform the automatic page programming
again because writing to the page has not been normally terminated.
The automatic page programming operation is allowed only once for a page already erased.
No programming can be performed twice or more times irrespective of the data cell value
whether it is "1" or "0." Note that rewriting to a page that has been once written requires
execution of the automatic block erase or automatic chip erase command before executing
the automatic page programming command again. Note that an attempt to rewrite a page
two or more times without erasing the content can cause damages to the device.
No automatic verify operation is performed internally to the device. So, be sure to read the
data programmed to confirm that it has been correctly written.
cycle of the command cycle is completed. On and after the fifth bus write cycle, data will be
written sequentially starting from the next address of the address specified in the fourth bus
write cycle (in the fourth bus write cycle, the page top address will be command written) (32
bits of data is input at a time). Be sure to use the 32-bit data transfer command in writing
commands on and after the fourth bus cycle. In this, any 32-bit data transfer commands
shall not be placed across word boundary. On and after the fifth bus write cycle, data is
command written to the same page area. Even if it is desired to write the page only partially,
it is required to perform the automatic page programming for the entire page. In this case,
the address input for the fourth bus write cycle shall be set to the top address of the page.
Be sure to perform command write operation with the input data set to "1" for the data cells
not to be set to "0." For example, if the top address of a page is not to be written, set the
input data of the fourth bus write cycle to 0xFFFFFFFF to command write the data.
Once the fourth bus cycle is executed, it is in the automatic programming operation. This
condition can be checked by monitoring the register bit FCFLCS [0] <RDY/BSY> (See
Table 20-15). Any new command sequence is not accepted while it is in automatic page
programming mode. If it is desired to stop operation, use the hardware reset function. Be
careful in doing so because data cannot be written normally if the operation is interrupted.
Writing to data cells is automatically performed by an internal sequencer and no external
The automatic page programming operation starts when the third bus write
