Notes: 1. AC measurements assume that VIH = 2.4 V, VIL = 0.4 V and tT = 1 ns.
2. The reference level for timing of input signals is 1.4 V.
1.4V
3. Output load.
50Ω
Z=50Ω
Output
30pF (External Load)
4. The access time is defined at 1.4 V.
5. If tT is longer than 1 ns, then the reference level for timing of input signals is VIH and VIL.
6. It is necessary to operate auto-refresh 4096 cycles within tREF.
