AC measurements assume tT = 2 ns. 2. An initial pause of 200us is required after power followed by a minimum of eight initialization cycles (any combination of cycles containing RAS-only refresh or CAS-before-RAS refresh). 3. Operation with 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. 4. Operation with 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 exclusively by tAA. 5. Either tODD or tCDD must be satisfied. 6. Either tDZO or tDZC must be satisfied. 7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition times are measured between VIH (min) and VIL (max). 8. Assumes that tRCD <= tRCD (max) and tRAD <= tRAD (max). If tRCD or tRAD is greater than the maximum recommended value shown in this table, tRAC exceeds the value shown. 9. Measured with a load circuit equivalent to 1TTL loads and 100pF. 10. Assumes that tRCD >= tRCD (max) and tRAD <= tRAD (max). 11. Assumes that tRCD <= tRCD (max) and tRAD >= tRAD (max). 12. Either tRCH or tRRH must be satisfied for a read cycles. 13. tOFF (max) and tOEZ (max) define the time at which the outputs achieve the open circuit condition and are not referred to output voltage levels. 14. tWCS, tRWD, tCWD, tAWD and tCPW are not restrictive operating parameters. 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 open circuit(high impedance) throughout the entire cycle; if tRWD>=tRWD(min), tCWD>=tCWD(min), and tAWD>=tAWD(min), or tCWD>=tCWD(min) tAWD >= tAWD (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 out (at access time) is indeterminate. Rev 0.1 / Apr’01 GM71V18163C GM71VS18163CL 15. These parameters are referred to UCAS and LCAS leading edge in early write cycles and to WE leading edge in delayed write or read-modify-write cycles. 16. tRASP defines RAS pulse width in EDO mode cycles. 17. Access time is determined by the longer of tAA or tCAC or tACP. 18. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. After RAS is reset, if tOEH>=tCWL, the I/O pin will remain open circuit (high impedance): if tOEH<=tCWL, invalid data will be out at each I/O. 19. When both LCAS and UCAS go low at the same time, all 16-bits data are written into the device. LCAS and UCAS cannot be staggered within the same write/read cycles. 20. All the Vcc and Vss pins shall be supplied with the same voltages. 21. tASC, tCAH, tRCS, tWCS, tWCH, tCSR and tRPC are determined by the earlier falling edge of UCAS or LCAS. 22. tCRP, tCHR, tRCH, tACP and tCPW are determined by the later rising edge of UCAS or LCAS. 23. tCWL, tDH, tDS and tCHS should be satisfied by both UCAS and LCAS. 24. tCP is determined by the time that both UCAS and LCAS are high. 25. tHPC(min) can be achieved during a series of EDO page made write cycles or EDO mode write cycles. It both write and read operation are mixed in a EDO mode RAS cycle(EDO mode mix cycle (1),(2)) minimum Value of CAS cycle (tCAS+tCP+2tT) becomes greater than the specified tHPC (min) value. The value of CAS cycle time of mixed EDO mode is shown in EDO mode mix cycle (1) and (2). 26. When output buffers are enabled once, sustain the low impedance state until valid data is obtained. When output buffer is turned on and off within a very short time , generally it causes large Vcc/Vss line noise, which causes to degrade VIH min/VIL max level. 27. Data output turns off and becomes high impedance from later rising edge of RAS and CAS. Hold time and turn off time are specified by the timing specification of later rising edge of RAS and CAS between tOHR and tOH, and between tOFR and tOFF. 28. EDO Hi-Z control by OE or WE. OE rising edge disables data outputs. When OE goes high during CAS high, the data will not come out until next CAS access. When WE goes low during CAS high, the data will not come out until next CAS access. 29. Please do not use tRASS timing, 10us<=tRASS<=100us. During this period, the device is in transition state from normal operation mode to self refresh mode. If tRASS>=100us, then RAS 30.
