1.An initial pause of 200s 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 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. 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 anf 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. 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 readwrite cycles. 11. 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.

1. An initial pause of 200us is required after power-up followed by any 8 /RAS-only or /CAS-before-/RAS refresh cycles before proper device operation is achieved. 2. Input voltage levels are Vih/Vil. 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 1 TTL 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 tCAC. 5. Assumes that tRCD tRCD(max). 6. This parameter defines the time at which the output achieves the open circuit and is not referenced for V OH or VOL. 7. tWCS is non-restrictive operating parameter. It is included in the data sheet as electrical characteristics only. If tWCS tWCS(min), the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. These parameters are referenced to the /CAS leading edge in early write cycles. 10. Operation within the tRAD(max) limit insures that tRAC(max) can be met. tRAD(max) is specified as reference point only. If tRAD is greater than the specified tRAD(max) limit access time is controlled by tAA. 11. tASC 6ns, Assume t T=2.0ns. 12. If /RAS goes high before /CAS high going, the open circuit condition of the output is achieved by /CAS high going. If /CAS goes high before /RAS high going , the open circuit condition of the output is achieved by /RAS going. .
