Fast Program commands
There are four Fast Program commands available to improve the programming throughput,
by writing several adjacent words or bytes in parallel. The Double, Quadruple and Octuple
Byte Program commands are available for x8 operations, while the Double Quadruple Word
Program command are available for x16 operations.
Fast Program commands can be suspended and then resumed by issuing a Program
Suspend command and a Program Resume command, respectively (see

Double Byte Program command
The Double Byte Program command is used to write a page of two adjacent Bytes in
parallel. The two bytes must differ only in DQ15A-1. Three bus write cycles are necessary to
issue the Double Byte Program command.

Quadruple Byte Program command
The Quadruple Byte Program command is used to write a page of four adjacent Bytes in
parallel. The four bytes must differ only for addresses A0, DQ15A-1. Five bus write cycles
are necessary to issue the Quadruple Byte Program command.

The first bus cycle sets up the Double Byte Program Command.
The second bus cycle latches the Address and the Data of the first byte to be written.
The third bus cycle latches the Address and the Data of the second byte to be written.
The first bus cycle sets up the Quadruple Byte Program Command.
The second bus cycle latches the Address and the Data of the first byte to be written.
The third bus cycle latches the Address and the Data of the second byte to be written.
The fourth bus cycle latches the Address and the Data of the third byte to be written.
The fifth bus cycle latches the Address and the Data of the fourth byte to be written and
starts the Program/Erase Controller.
