4.2
Fast Program commands
There are five Fast Program commands available to improve the programming throughput,
by writing several adjacent words or bytes in parallel:
●
Quadruple and Octuple Byte Program, available for x8 operations
●
Double and Quadruple Word Program, available for x16 operations
●
Write to Buffer and Program
Fast Program commands can be suspended and then resumed by issuing a Program
Suspend command and a Program Resume command, respectively (see Section 4.1.8:
4.2.1
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.
1.
The first bus cycle sets up the Double Byte Program Command.
2.
The second bus cycle latches the Address and the Data of the first byte to be written.
3.
The third bus cycle latches the Address and the Data of the second byte to be written.
Note:
It is not necessary to raise VPP/WP to 12V before issuing this command.
4.2.2
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:
1.
The first bus cycle sets up the Quadruple Byte Program Command.
2.
The second bus cycle latches the Address and the Data of the first byte to be written.
3.
The third bus cycle latches the Address and the Data of the second byte to be written.
4.
The fourth bus cycle latches the Address and the Data of the third byte to be written.
5.
The fifth bus cycle latches the Address and the Data of the fourth byte to be written and
starts the Program/Erase Controller.
Note:
It is not necessary to raise VPP/WP to 12V before issuing this command.
