performed in the remaining two cycles. To execute Fast Program, input the Fast Program command. Writes in this mode uses
the Fast Program command but operation is the same at that for ordinary Auto-Program. The status of the device is indicated
by the Hardware Sequence flag and read operations can be performed as usual. To exit this mode, the Fast Program Reset
command must be input. When the command is input, the device will return to Read Mode.
10.13. Acceleration Mode
automatically sets the device to Acceleration Mode. In Acceleration Mode, Block Protect Mode changes to Temporary Block
Unprotect Mode. Write Mode changes to Fast Program Mode. Modes are switched by the
need for a Temporary Block Unprotect operation or to set or reset Fast Program Mode. Operation of Write is the same as in

In this mode, the Programming time for 64M bit is less than 60% compared with the Auto program mode. In word mode, input
the page program command during first bus write cycle to third bus writes cycle. Input program data and address of (A0, A1,
