HYPER PAGE MODE OPERATION
The hyper page mode operation provides faster memory access and lower power dissipation. The hyper page
mode is implemented by keeping the same row address and strobing in successive column addresses. To
satisfy these conditions, RAS is held Low for all contiguous memory cycles in which row addresses are common.
For each page of memory (within column address locations), any of 512
×
16-bits can be accessed and, when
multiple MB81V4265Ss are used, CAS is decoded to select the desired memory page. Hyper page mode
operations need not be addressed sequentially and combinations of read, write, and/or read-modify-write cycles
are permitted. Hyper page mode features that output remains valid when CAS is inactive until CAS is reactivated.
