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 1TTL loads and 100pF 4.Operation within the tRCD(max) limit insures that tRAC(max) can be met. tRCD(max) is specified as a reference point only. If tRCD is greater than the specified tRCD(max) limit, then access time is controlled exclusively by t CAC. 5.Assumes that tRCD ≥ tRCD(max) 6.This parameter defines the time at which the output achieves the open circuit condition and is not referenced to V OH or VOL. 7. tWCS, tRWD, tCWD and tAWD are non restrictive operating parameter. They are included in the data sheet as electrical 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 the data output will contain the data read from the selected address. If neither of the above conditions are satisfied, The condition of the data out is indeternimated. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. Operation within the tRAD(max) limit insures that tRAC(max) can be met. tRAD(max) is specified as a reference point only. If tRAD is greater than the specified tRAD(max) limit. then access time is controlled by tAA. 10. If /RAS goes to high before /CAS high going, the open circuit condition of the output is achieved by /CAS high going. If /Cas goes to high before /RAS high going, the open circuit condition of the output is achieved by /RAS high going. 11.tASC ≥ 6ns URL:www.hbe.co.kr REV.1.0.
