NOTES 1.An initial pause of 200ms is required after power-up followed by any 8 /RAS-only or /CAS-before-/RAS refresh cycles before proper device operation is achieved. 2.VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Transition times are measured between VIH(min) and VIL(max) and are assumed to be 5ns for all inputs. 3.Measured with a load equivalent to 2TTL loads and 100pF 4.Operation within the t RCD(max) limit insures that t RAC(max) can be met. t RCD(max) is specified as a reference point only. If t RCD is greater than the specified t RCD(max) limit, then access time is controlled exclusively by t CAC. 5.Assumes that t RCD tRCD(max) 6. tAR, tWCR, tDHR are referenced to tRAD(max) 7.This parameter defines the time at which the output achieves the open circuit condition and is not referenced to V OH or VOL. 8. tWCS, tRWD, tCWD and tAWD are non restrictive operating parameter. They are included in the data sheet as e lectrical characteristic only. If t WCS tWCS(min) the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle. 9. Either tRCH or tRRH must be satisfied for a read cycle. 10. These parameters are referenced to the /CAS leading edge in early write cycles and to the /W leading edge in read write cycles. 11. Operation within the t RAD(max) limit insures that t RAC(max) can be met. t RAD(max) is specified as a reference point only. If t RAD is greater than the specified t RAD(max) limit. then access time is controlled by t AA.
