AC measurements assume t T = 2ns. 2. An initial pause of 100 µ s is required after power up, and it followed by a minimum of eight initialization cycles (RAS - only refresh cycle or CAS - before - RAS refresh cycle). If the internal refresh counter is used, a minimun of eight CAS - before - RAS refresh cycles are required. 3. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. 4. All the VCC and VSS pins shall be supplied with the same voltages. 5. tRAS(min) = tRWD(min)+t RWL(min)+tT in read-modify-write cycle. 6. tCAS (min) = tCWD(min)+tCWL(min)+tT in read-modify-write cycle. 7. tASC(min), tRCS (min), tWCS(min), and tRPC are determined by the falling edge of CAS . 8. t RCD(max) is specified as a reference point only, and tRAC (max) can be met with the tRCD(max) limit. Otherwise, tRAC is controlled exclusively by tCAC if tRCD is greater than the specified tRCD(max) limit. 9. tRAD(max) is specified as a reference point only, and tRAC(max) can be met with the tRAD(max) limit. Otherwise, tRAC is controlled exclusively by tAA if tRAD is greater than the specified tRAD(max) limit. 10. tCRP, tCHR , tRCH, tCPA and tCPW are determined by the rising edge of CAS . 11. V IH(min) and VIL(max) are reference levels for measuring timing or input signals. Therefore, transition time is measured between VIH and VIL. 12. Assumes that t RCD ≤ tRCD(max) and tRAD ≤ tRAD(max). If t RCD or tRAD is greater than the maximum recommended value shown in this table, tRAC exceeds the value shown. 13. Assumes that tRCD ≥ t RCD (max) and tRAD ≤ t RAD (max). ≥ tRAD (max). 14. Access time is determined by the maximum of tAA , tCAC, tCPA. 15. Assumes that t RCD ≤ tRCD (max) and t RAD 16. Either tRCH or tRRH must be satisfied for a read cycle. 17. tOFF(max) and tOEZ(max) define the time at which the output achieves the open circuit condition (high impedance). t OFF is determined by the later rising edge of RAS or CAS. 18. tWCS, tRWD, tCWD, and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS ≥ t WCS (min), the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If tRWD tCWD ≥ tRWD (min), ≥ t CWD (min), t AWD ≥ t AWD (min) and tCPW ≥ tCPW (min), the cycle is a read-modify-write and the data output will contain data read from the selected cell. If neither of the above sets of conditions is satisfied, the condition of the data output (at access time) is indeterminate. 19. These parameters are referenced to CAS separately in an early write cycle and to WE edge in a delayed write or a read-modify-write cycle. 20. tRASP defines RAS pulse width in EDO page mode cycles.
