DYNAMIC RAM· MSC2304YS9/KS9 •NOTES: 11213141516171An initial pause of 1oolols is required after power-up followed by any 8 ~ cycles (Examples; RASonlyl before proper device operation is achieved.AC measurements assume tT = 5 ns.VIH (Min.) and Vil (Max.) are reference levels for measuring timing of input signals. Also, transitiontimes are measured between VIH and Vil.Assumes that tACO < tACO (max.l.If tACO is greater than the maximum recommended value shown in this table, tAAC will increase bythe amount that tACO exceeds the values shown.Assumes that tACO < tACO (max.)Measured with a load circuit equivalent to 2 TTL loads and 100pF.Operation within the tACO (max.1 limit insures that tAAC (max.) can be met. tACO (max.1 is specifiedas a reference point only; if tACO is greater than the specified tACO (max.) limit, then accesstime is controlled exclusively by tCAC.READ CYCLE TIMING~------------------tAC------------------~VIH _ ---~ f...---tAR------
