An initial pause of 200us is required after power-up followed by any 8 RAS-only or CAS-before-RAS refresh cycles before proper device operation is achieved. 2. VIH(min) and V IL(max) are reference levels for measuring timing of input signals. Transition times are measured between V IH(min) and V IL(max) and are assumed to be 5ns for all inputs. 3. Measured with a load equivalent to 2 TTL loads and 100pF. 4. Operation within the tRCD(max) limit insures 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 exclusively by tCAC. 5. Assumes that tRCDtRCD(max). 6. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to V OH or VOL. 7. tWCS is non-restrictive operating parameter. It is included in the data sheet as electrical characteristic s only. If tWCStWCS(min), the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. These parameters are referenced to the CAS leading edge in early write cycles and to the W leading edge in read-write cycles. 10. Operation within the tRAD(max) limit insures that tRAC(max) can be met. tRAD(max) is specified as reference point only. If tRAD is greater than the specified tRAD(max) limit, then access time is controlled by tAA. 11. 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 level. 12. If RAS goes to high before CAS high going, the open circuit condtion of the output is achieved by CAS high going. If CAS goes to high before RAS high going, the open circuit condtion of the output is achieved by RAS high going. 13. tASCtCP min 14. In order to hold the address latched by the first CAS going low, the parameter tCLCH must be met. -7- Rev. 0.0 (Nov. 1997) DRAM MODULE READ CYCLE KMM5362205C2W/C2WG tRC tRAS RAS VIH VIL - tRP tCRP CAS VIH VIL - tCSH tRCD tRSH tCAS tCRP tRAD tASR A VIH VIL - tRAH tASC tRAL tCAH COLUMN ADDRESS ROW ADDRESS tRCS W VIH VIL - tRCH tRRH tAA tCEZ tRAC OPEN tCAC tCLZ tREZ DATA-OUT tWEZ DQ VOH VOL - Dont care Undefined -8- Rev. 0.0 (Nov. 1997) DRAM MODULE WRITE CYCLE ( EARLY WRITE ) NOTE : DOUT = OPEN KMM5362205C2W/C2WG tRC tRAS RAS VIH VIL - tRP tCSH tCRP CAS VIH VIL - tRCD tRAD tRSH tCAS tCRP tASR A VIH VIL - tRAH tASC tRAL tCAH COLUMN ADDRESS ROW ADDRESS tCWL tRWL tWCS W VIH VIL - tWCH tWP tDS DQ VIH VIL - tDH DATA-IN Dont care Undefined -9- Rev. 0.0 (Nov. 1997) DRAM MODULE HYPER PAGE READ CYCLE KMM5362205C2W/C2WG tRASP RAS VIH VIL o tRP tCSH tCRP CAS VIH VIL - tRHCP tHPC tCP tHPC tCAS tCP tHPC tCAS tCP tCAS tRCD tCAS tRAD tASR A VIH VIL - tRAH tASC ROW ADDR tCAH tASC tCAH tASC tCAH COLUMN ADDR tASC tCAH tREZ COLUMN ADDRESS COLUMN ADDRESS COLUMN ADDRESS tRRH tRCS W VIH VIL - tRCH tCPA tCAC tAA tCAC tAA tCPA tAA tCAC tRAC tDOH VALID DATA-OUT tCAC tAA tCPA tDOH VALID DATA-OUT tDOH VALID DATA-OUT VALID DATA-OUT DQ VOH VOL - tCLZ Dont care Undefined - 10 - Rev. 0.0 (Nov. 1997) DRAM MODULE HYPER PAGE WRITE CYCLE ( EARLY WRITE ) NOTE : DOUT = OPEN KMM5362205C2W/C2WG tRASP RAS VIH VIL o tRP tRHCP tCRP CAS VIH VIL - tHPC tRCD tCAS tRAD tCSH tASC tCP tCAS o tHPC tCP tRSH tCAS tASR A VIH VIL - tRAH tCAH tASC tCAH o tASC tCAH ROW ADDR.
