DESCRIPTION
The hyper page mode of operation permits faster successive memory operations at multiple column locations of the same row
address. This operation is performed by strobing in the row address and maintaining RAS at a Low level and WE at a High level
during all successive memory cycles in which the row address is latched. The address time is determined by t
CAC
, t
AA
, t
CPA
, or
t
OEA
, whichever one is the latest in occurring.
