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 tha tRCD≥tRCD(max). 6. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to VOH or VOL. 7. tWCS, tRWD, tCWD, tAWD and tCPWD are not restrictive operating parameter. They are 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. If tRWD≥tRWD(min), tCWD≥tCWD(min), tAWD≥tAWD(min) and tCPWD≥tCPWD(min). The cycle is a read-modify-write cycle and the data out will contain data read from the selected cell. If neither of the above sets of conditions is satisfied, the condition of data out(at access time) is indeterminate. 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, then access time is controlled by tAA. 11. 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. 12. tASC≥6ns. 13. The timing skew from the DRAM to the DIMM resulted from the addition of buffers. 14. tASC, tCAH are referenced to the earlier CAS falling edge. 15. tCP is specified from the last CAS rising edge in the previous cycle to the first CAS falling edge in the next cycle. 16. tCWD is referenced to the later CAS falling edge at word readmodify-write cycle. 17. tCWL is specified from W falling edge to the earlier CAS rising edge. 18. tCSR is referenced to earlier CAS falling low before RAS transition low.
