Note 13: The timing requirements are assumed tT =5ns.
14: VIH(min) and VIL(max) are reference levels for measuring timing of input signals.
15: 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.
16: tRAD(max) is specified as a reference point only. If tRAD ≥ tRAD(max) and tASC ≤ tASC(max), access time is controlled exclusively by tAA.
17: tASC(max) is specified as a reference point only. If tRCD ≥ tRCD(max) and tASC ≥ tASC(max), access time is controlled exclusively by tCAC.
18: Either tDZC or tDZO must be satisfied.
19: Either tCDD or tODD must be satisfied.
20: tT is measured between VIH(min) and VIL(max).
