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 pins are latched on the falling edge of CAS 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.
During one cycle is achieved, the input/output timing apply the same manner as the former cycle.
