Write start time
Notes: 1. t
is defined as the time at which the outputs achieve the open circuit conditions and are no
longer driven.
2. Use this device in longer cycle than this value.
3. t
must be longer than this value unless polling techniques or RDY/
Busy
are used. This
device automatically completes the internal write operation within this value.
4. Next read or write operation can be initiated after t
DW
if polling techniques or RDY/
Busy
are
used.
5. A6 through A12 are page addresses and these addresses are latched at the first falling edge
of
