Notes
22. VIH overshoot: VIH (MAX) = VDDQ + 2V for a pulse width ≤ 3ns, and the pulse width
cannot be greater than one-third of the cycle rate. VIL undershoot: VIL (MIN) = –2V for
a pulse width ≤ 3ns.
23. The clock frequency must remain constant (stable clock is defined as a signal cycling
within timing constraints specified for the clock pin) during access or precharge
states (READ, WRITE, including tWR, and PRECHARGE commands). CKE may be
used to reduce the data rate.
24. Auto precharge mode only. The precharge timing budget (tRP) begins 6ns/7ns/7.5ns/
7ns after the first clock delay, after the last WRITE is executed.
25. Precharge mode only.
26. JEDEC and PC100 specify three clocks.
27. tAC for -75/-7E at CL = 3 with no load is 4.6ns and is guaranteed by design.
28. Parameter guaranteed by design.
29. PC100 specifies a maximum of 4pF.
30. PC100 specifies a maximum of 5pF.
31. PC100 specifies a maximum of 6.5pF.
32. For -75, CL = 3 and tCK = 7.5ns; for -7E, CL = 2 and tCK = 7.5ns; for -6, CL = 3 and
tCK = 6ns.
33. CKE is HIGH during refresh command period tRFC (MIN) else CKE is LOW. The IDD6
limit is actually a nominal value and does not result in a fail value.
34. The -6 speed grade does not support CL = 2.
