5 / 22 page  MITSUBISHI LSIs M5M417400CJ,TP-5,-6,-7,-5S,-6S,-7S FAST PAGE MODE 16777216-BIT (4194304-WORD BY 4-BIT) DYNAMIC RAM 5 TIMING REQUIREMENTS (For Read, Write, Read-Modify-Write, Refresh, and Fast-Page Mode Cycles) (Ta = 0 ~ 70°C, VCC = 5V ± 10%, VSS = 0V, unless otherwise noted. See notes 12, 13) Note 12: The timing requirements are assumed tT = 5ns. 13: VIH(min) and VIL(max) are reference levels for measuring timing of input signals. 14: 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. tRCD(min) is specified as tRCD(min) = tRAH(min) + 2tH + tASC(min). 15: tRAD(max) is specified as a reference point only. If tRAD ≥ tRAD(max) and tASC ≤ tASC(max), access time is controlled exclusively by tAA. 16: tASC(max) is specified as a reference point only. If tRCD ≥ tRCD(max) and tASC ≥ tASC(max), access time is controlled exclusively by tCAC. 17: Either tDZC or tDZO must be satisfied. 18: Either tCDD or tODD must be satisfied. 19: tT is measured between VIH(min) and VIL(max). Read and Refresh Cycles Note 20: Either tRCH or tRRH must be satisfied for a read cycle.
