Fast Program commands
The M29EW offers a set of Fast Program commands to improve the programming
throughput:

After programming has started, Bus Read operations in the memory output the Status
Register content. Write to Buffer Program command can be suspended and then resumed
by issuing a Program Suspend command and a Program Resume command, respectively
(see
command).
After the fast program operation has completed, the memory will return to the Read mode,
unless an error has occurred. When an error occurs Bus Read operations to the memory
will continue to output the Status Register. A Read/Reset command must be issued to reset
the error condition and return to Read mode. One of the Erase commands must be used to
set all the bits in a block or in the whole memory from ‘0’ to ‘1’.
Typical program times are given in
Double Byte/Word Program command
The Double Byte/Word Program command for 32-Mbit and 64-Mbit devices is used to write
a page of two adjacent bytes/words in parallel. The two bytes/words must differ only for the
address A-1 or A0, respectively. Three bus write cycles are necessary to issue the Double
Byte/Word Program command:

The first bus cycle sets up the Double Byte/Word Program command.
The second bus cycle latches the Address and the Data of the first byte/word to be
programmed.
The third bus cycle latches the Address and the Data of the second byte/word to be
programmed and starts the Program/Erase Controller.
