Note 14: The timing requirements are assumed tT =3ns.
15: VIH(min) and VIL(max) are reference levels for measuring timing of input signals.
16: tRCD(max) is specified as a reference point only. If tRCD is less than tRCD(max), access time is tRAC. If tRCD is greater than tRCD(max), access
time is controlled exclusively by tCAC or tAA.
17: tRAD(max) is specified as a reference point only. If tRAD ≤ tRAD(max) and tASC ≤ tASC(max), access time is controlled exclusively by tAA.
18: tASC(max) is specified as a reference point only. If tRCD ≥ tRCD(max) and tASC ≥ tASC(max), access time is controlled exclusively by tCAC.
19: tDZC must be satisfied.
20: Either tRDD or tCDD or tODD must be satisfied.
21: tT is measured between VIH(min) and VIL(max).
