An initial pause of 200µs is required after power-up followed by any 8 RAS only Refresh or CAS before RAS Refresh cycles to initialize the internal circuit. 2. VIH(min.) and VIL(min.) are reference levels for measuring timing of input signals. Transition times are measured between VIH(min.) and VIL(max.) are assumed to be 5ns for all inputs. 3. Measured with an equivalent to 1 TTL loads and 50pF. 4. For read cycles, the access time is defined as follows: Input Conditions Access Time tRAC(MAX.) tRAD ≤ tRAD(MAX.) and tRCD ≤ tRCD(MAX.) tAA(MAX.) tRAD(max.)< tRAD and tRCD ≤ tRCD(MAX.) tRCD(max.)< tRCD tCACMAX.) tRAD(MAX.) and tRCD(MAX.) indicate the points which the access time changes and are not the limits of operation. 5. tWCS,tRWD,tCWD and tAWD are non restrictive operating parameters. They are included in the data sheet as electric characteristics only. If tWCS ≥ tWCS(min.), the cycle is an early write cycle and the data output will remain high impedance for the duration of the cycle.If tCWD ≥ tCWD(min.),tRWD ≥ tRWD (min.) and tAWD ≥ tAWD(min.), then the cycle is a read-modify-write cycle and the data output will contain the data read from the selected address. If neither of the above conditions is satisfied, the condition of the data out is indeterminate. 6. tAR,tWCR, and tDHR are referenced to tRAD(max.). 7. tOFF(max.) and tOEZ(max.) define the time at which the output achieves the open circuit condition and are not referenced to VOH or VOL. 8. tCRP(min) requirement should be applicable for RAS , CAS cycle preceded by any cycles. 9. Either tRCH(min.) or tRRH(min.) must be satisfied for a read cycle. 10. tWP(min.) is applicable for late write cycle or read modify write cycle. In early write cycles,tWCH(min.) should be satisfied. 11.This specification is referenced to CAS falling edge in early write cycles and to WE falling edge in late write or read modify write cycles.
