Address Key

32M
The first cycle reads from the most significant address (MSB).
The second and third cycle are to write back the data (RDa) read by first cycle. If the second or
third cycle is written into the different address, the program is cancelled, and the data written by
the second or third cycle is valid as a normal write operation.
The fourth and fifth cycles write to MSB. The data from the fourth and fifth cycles is “don’t care.”
If the fourth or fifth cycles are written into different address, the program is also cancelled but
write data might not be written as normal write operation.
The last cycle is to read from specific address key for mode selection.
Once this program sequence is performed from a Partial mode to the other Partial mode, the writ-
ten data stored in memory cell array can be lost. So, it should perform this program prior to
regular read/write operation if Partial mode is used.
The address key has following format.
