(v cc and v ccq must be powered up simultaneously. v ss and v ssq must be at same potential.) the two auto refresh command wake-ups should be repeated any time the tref refresh requirement is exceeded. 7. ac characteristics assume t t = 1ns. 8. in addition to meeting the transition rate speci? cation, the clock and cke must transit between v ih and v il (or between v il and v ih ) in a mono-tonic manner. 9. outputs measured at 1.5v with equivalent load: q 50pf 10. t hz de? nes the time at which the output achieves the open circuit condition; it is not a reference to v oh or v ol . the last valid data element will meet t oh before going high-z. 11. ac timing and i dd tests have v il = 0v and v ih = 3v with timing referenced to 1.5v crossover point. if the input transition time is longer than 1ns, then the timing is referenced at v il (max) and v ih (min) and no longer at the 1.5v crossover point. 12. other input signals are allowed to transition no more than once every two clocks and are other-wise at valid v ih or v il levels. 13. i dd speci? cations are tested after the device is properly initialized. 14. timing actually speci? ed by t cks ; clock(s) speci? ed as a reference only at minimum cycle rate. 15. timing actually speci? ed by t wr plus t rp ; clock(s) speci? ed as a reference only at minimum cycle rate. 16. timing actually speci? ed by t wr . 17. required clocks are speci? ed by jedec functionality and are not dependent on any timing parameter. 18. the i dd current will increase or decrease proportionally according to the amount of frequency alteration for the test condition. 19. address transitions average one transition every two clocks. 20. clk must be toggled a minimum of two times during this period. 21. based on t ck = 10ns for 10, and t ck = 7.5ns for 7 and 7.5. 22. v ih overshoot: v ih (max) = v ccq + 2v for a pulse width 3ns, and the pulse width cannot be greater than one third of the cycle rate. v il under-shoot: v il (min) = -2v for a pulse width 3ns. 23. the clock frequency must remain constant (stable clock is de? ned as a signal cycling within timing constraints speci? ed for the clock pin) during access or precharge states (read, write, including t wr , and precharge commands). cke may be used to reduce the data rate. 24. auto precharge mode only. the precharge timing budget (t rp ) begins 7ns for 7; 7.5ns for 7.5 and 7.5ns for 10 after the ? rst clock delay, after the last write is executed. may not exceed limit set for precharge mode. 25. precharge mode only. 26. jedec and pc133, pc100 specify three clocks. 27. t ac for 7/7.5 at cl = 3 with no load is 4.6ns and is guaranteed by design. 28. parameter guaranteed by design.
