Notes: 1. A start-up delay of 200µs is required after power-up, followed by a minimum of eight initialization cycles (/RAS only refresh or /CAS before /RAS refresh) before proper device operation is achieved. The AC characteristics assumes tT = 2ns. VIH(Min.) and VIL(Max.) are reference levels for measuring input timing signals. Transition time (tT) are measured between VIH and VIL. This parameter is measured with a load circuit equivalent to 2TTL loads and 100pF. Operation within the tRCD(Max.) limit ensures that tRAC(Max.) can be met. tRCD(Max.) is specified as a reference point only. If tRCD is greater than the specified tRCD(Max.) limit, then the access time is controlled by tCAC. Operation within the tRAD(Max.) limit ensures that tRAC(Max.) can be met. tRAD(Max.) is specified as a reference point only. If tRAD is greater than the specified tRAD(Max.) limit, then the access time is controlled by tAA. tCEZ(Max.), tREZ(Max.) and tWEZ(Max.) define the time at which the output achieves the open circuit condition and are not referenced to output voltage levels. tCEZ and tREZ must be satisfied for open circuit condition. tRCH or tRRH must be satisfied for a read cycle.
