Notes: 1. A start-up delay of 200s 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. 2. The AC characteristics assume tT = 2ns. 3. VIH(Min.) and VIL(Max.) are reference levels for measuring input timing signals. Transition times (tT) are measured between VIH and VIL. 4. This parameter is measured with a load circuit equivalent to 1 TTL load and 100pF. The output timing reference levels are VOH = 2.0V and VOL = 0.8V. 5. 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. 6. 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. 7. tCEZ(Max.), tREZ(Max.), tWEZ(Max.) and tOEZ(Max.) define the time at which the output achieves the open circuit condition and are not referenced to output voltage levels. 8. tCEZ or tREZ must be satisfied for open circuit condition. 9. tRCH or tRRH must be satisfied for a read cycle. 10. tWCS, tCWD, tRWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS tWCS(Min.), then the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If tCWD tCWD(Min.), tRWD tRWD(Min.), tAWD tAWD(Min.) and tCPWD tCPWD(Min.), then the cycle is a read modify write cycle and data out will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, then the condition of the data out (at access time) is indeterminate.
