DESCRIPTION
The fast page mode write cycle is executed in the same manner as the fast page mode read cycle except for the states of WE and OE
are reversed. Data appearing on the DQ pins is latched on the falling edge of CAS and written into memory. During the fast page mode
write cycle, including the delayed (OE) write and read-modify-write cycles, t
CWL
must be satisfied.
