An initial pause of 200µs is required after power-up followed by 8 /RAS only refresh cycles before proper device operation is achieved. In case of using internal refresh counter, a minimum of 8 CBR refresh cycles instead of 8 /RAS-only refresh cycles are required. 2 tASC ≥ tCP(min), assume tT=3ns. 3. VIH(min.) and VIL(max.) are reference levels for measuring timing of input signals. Transition times are measured between VIH(min.) and VIL(max.) 4. The minimum specifications are used only to indicate cycle time at which proper operation over the full temperature range (TA=0 to 70¡ ÆC) is assured. 5. Measured at VOH=2.0V and VOL=0.8V with a load equivalent to 1TTL loads and 100pF. 6. 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 access time is controlled by tCAC. 7. 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 access time is controlled by tAA. 8. tWEZ, tREZ, tCEZ and tOEZ define the time at which the output achieves the open circuit condition and is not referenced to output voltage levels. 9. Either tRCH or tRRH must be satisfied for a read cycle. 10.These parameters are referenced to /LCAS or /UCAS leading edge in early write cycles and to /WE leading edge in read-modify-write cycles and late write cycle. 11.tWCS, tRWD, tCWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS ≥ tWCS(min.), the cycle is an early write cycle and data out pin will remain open circuit (high impedance) through the entire cycle. If tRWD ≥ tRWD(min.), tCWD ≥ tCWD(min.), tAWD ≥ tAWD(min), and tCPWD ≥ tCPWD(min.), 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, the condition of the data out (at access time) is indeterminate. 12.If /RAS goes to high before /CAS high going,the open circuit condition of the output is achieved by /CAS high going. If /CAS goes to high before /RAS high going,the open circuit condition of the output is achieved by /RAS high going. 13.tASC,tCAH are referenced to the earlier /CAS falling edge. 14.tCP and tCPT are measured when /CAS is high state. 15.tCWD is referenced to the later /CAS falling edge at word read-modifiy-write cycle. 16.tCWL must be satisfied by /CAS for 8-bit access cycles. 17.tCSR is referenced to the earlier /CAS falling before /RAS transition low. 18.tCHR is referenced to the later /CAS rising high after /RAS transition low.
