DESCRIPTION
The hyper page mode early write cycle is executed in the same manner as the hyper page mode read cycle except the states of
WE and OE are reversed. Data appearing on the DQ
1
to DQ
8
is latched on the falling edge of LCAS and one appearing on the DQ
9
to DQ
16
is latched on the falling edge of UCAS and the data is written into the memory. During the hyper page mode early write
cycle, including the delayed (OE) write and read-modify-write cycles, t
CWL
must be satisfied.
