Note reference levels measuring timing inputs signals.Also,transition times measured between initial pause 500us required after power-up followed cycles before proper device operation achived. measurements assume 5ns. Load 2TTL loads 100pF. Operation within tRCD limit insures that tRAC met.tRCD specified reference point only.If tRCD greater than specified tRCD limit,then access time controlled tCAC. Operation within tRAD limit insures that tRAC met.tRAD specified reference point only.If tRAD greater than specified tRAD limit,then access time controlled tAA. tOFF defines time which output achieves open circuit conditon referenced VOL. tCRP requirement should applicable /RAS-/CAS cycles preceeded cycle. Either tRRH tRCH must satisfied read cycle. These parameters referenced falling edge /CAS early write cycles.
