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. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. These parameter are referenced to the CAS leading edge in early write cycles and to the W leading edge in read-write 2. VIH(min) and VIL(max) are reference levels for measuring cycles. .com t4U.com DataShee timing of input signals. Transition times are measured between VIH(min) and VIL(max) and are assumed to be 5ns 10. Operation within the tRAD(max) limit insures that tRAC(max) for all inputs. can be met. tRAD(max) is specified as reference point only. If 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 VOH or VOL. 7. tWCS is non-restrictive operating parameter. It is included in the data sheet as electrical characteristics 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. 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 condition of the output is achieved by RAS high going. 13. tASCtCP min .com -5- Rev. 0.0 (Oct. 1999) DataSheet 4 U .com www..com DRAM MODULE READ CYCLE M53230224CE2/CJ2 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 tWEZ t4U.com DQ VOH VOL - tCAC .com tCLZ tRAC OPEN tREZ DATA-OUT DataShee Dont care Undefined .com -6- Rev. 0.0 (Oct. 1999) DataSheet 4 U .com www..com DRAM MODULE WRITE CYCLE ( EARLY WRITE ) NOTE : DOUT = OPEN M53230224CE2/CJ2 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 t4U.com DQ VIH VIL - .com tDS tDH DATA-IN DataShee Dont care Undefined .com -7- Rev. 0.0 (Oct. 1999) DataSheet 4 U .com www..com DRAM MODULE HYPER PAGE READ CYCLE M53230224CE2/CJ2 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 tCAH tASC tCAH tASC tCAH COLUMN ADDR tASC tCAH tREZ ROW ADDR COLUMN ADDRESS COLUMN ADDRESS COLUMN ADDRESS tRRH tRCS W VIH VIL - tRCH tCPA tCAC tAA tCAC tAA .com tCPA tAA tCAC tRAC tDOH VALID DATA-OUT t4U.com tCAC tAA tCPA tDOH DataShee tDOH VALID DATA-OUT VALID DATA-OUT DQ VOH VOL - VALID DATA-OUT tCLZ Dont care Undefined .com -8- Rev. 0.0 (Oct. 1999) DataSheet 4 U .com www..com DRAM MODULE HYPER PAGE WRITE CYCLE ( EARLY WRITE ) NOTE : DOUT = OPEN M53230224CE2/CJ2 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 o tASC tCAH ROW ADDR.
