PROGRAMME ALGORITHM
PROGRAMME
8 bit Operation
Write the programme setup command (40h) to the
address to be programmed. The next write sequence
will initiate the programming operation which will
end automatically as this period being controlled by
an internal timer and the data will be programmed.
To make sure that the data is
programmed correctly read data of the status
register. The read status register command (70h)
may or may not be applied to read the data after the
programme data input. If the data is programmed
step address and programme data according to the
above sequence.
The next address to be programmed should be
written with in a memory zone. After the last
programming operation, write the reset command
( FFh) in control register of the programmed memory
zones.
When overwriting bits programmed as “ 0 ” ,
programme “ 1 ” or the device reliability is affected.
16 bit operation
The algorithm of 16 bit programming is almost same
as the 8 bit programming. (Please refer to the
algorithm and the status of bus at programming)
PROGRAMME SUSPEND
8 bit Operation
The programme suspend is a command to generate
zone programme interruption in order to read or
data from another block of the selected memory
zone. It is necessary to write the erase suspend
command (B0h) in the programme algorithm.
The execution of the programme suspend can be
confirmed by reading data of the status register.
Then it is necessary to write the read command
( FFh) in control register in order to read data, after
reading the status register ’ s data.
After the programme resume command (D0h) is
written in the control register, the memory zone will
continue the programme operation.
16 bit Operation
Most of the algorithm of 16 bit programme
suspending is same as the one of the 8 bit
programme suspending.
(Please refer to the algorithm and the state of bus
at programme suspending.)
ERASE ALGORITHM
ERASE
8 bit Operation
Write the erase setup command (20h) and erase
confirm command (D0h) for the applicable block
address.
An erasure operation will then commence which
will be finished in 1.6s typical or less this being
automatically controlled by an internal timer.
To make sure that the data is erased correctly
and read data of the status register.
The read status register command (70h) may or may
not be applied to read the data after the erase
confirm command.
After erasure has completed write the reset
command ( FFh) to the control register, proceed
to the erase operation for the next memory block.
16 bit Operation
Most of the algorithm of 16 bit erasure is same as
the one of the 8 bit erasure.
(Please refer to the algorithm and the state of bus
at erasure.)
ERASE SUSPEND
8 bit Operation
The erase suspend is a command to generate block
erase interruption in order to read or programme
data from another block of the selected memory
zone. It is necessary to write the erase suspend
command (B0h) in the erase algorithm.
The execution of the erase suspend can be confirmed
by reading data of the status register.
Then it is necessary to write the read command
( FFh) in control register in order to read data, after
reading the status register ’ s data.
After the erase resume command (D0h) is written in
the control register, the memory block will continue
erase operation.
16 bit Operation
Most of the algorithm of 16 bit erase suspending is
same as the one of the 8 bit erase suspending.
(Please refer to the algorithm and the state of bus
at erase suspending.)
