NOTES (continued)
30. Last rising CASx# edge to next cycle’s last rising
CASx# edge.
31. Last rising CASx# edge to first falling CASx#
edge.
32. First DQs controlled by the first CASx# to go
LOW.
33. Last DQs controlled by the last CASx# to go
HIGH.
4 MEG x 16
FPM DRAM
34. Each CASx# must meet minimum pulse width.
35. Last CASx# to go LOW.
36. All DQs controlled, regardless CASL# and CASH#.
37. VIH overshoot: VIH (MAX) = VCC + 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, and the pulse width cannot be greater than
one third of the cycle rate.
4 Meg x 16 FPM DRAM
