A start-up delay of 200µs 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. -50 is measured with a load circuit equivalent to 2TTL load and 50pF, and -60/-70 is measured with a load circuit equivalent to 2TTL load and 100pF. 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 achieved the open circuit condition and are not referenced to output voltage levels. 8. tCEZ, and 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. 11. These parameters are referenced to the CAS, leading edges in an early write cycle, and to the WE leading edge in an OE control write cycle, or a read modify write cycle. 9/16 FEDD5117805F-01 1Semiconductor MSM5117805F TIMING CHART Read Cycle RAS tRC tRAS VIH tRP VIL tCSH tCRP CAS tRCD VIH tRAD VIL tRAL tASR Address WE OE tCRP tRSH tCAS VIH tRAH tASC Row VIL tCAH Column tRCS tRRH VIH tAA VIL tRCH tROH VIH VIL tCAC tRAC DQ tREZ tOEA tCEZ tOEZ tCLZ VOH Valid Data-out Open VOL “H” or “L” Write Cycle (Early Write) RAS tRC tRAS VIH tRP VIL tCSH tCRP CAS VIH tRAD VIL tRAL tASR Address VIH VIL tRAH tASC Row OE tCWL VIH tWCH tWP VIL tRWL VIH VIL tDS DQ tCAH Column tWCS WE tCRP tRSH tCAS tRCD VIH VIL tDH Valid Data-in Open “H” or “L” 10/16 FEDD5117805F-01 1Semiconductor MSM5117805F Read Modify Write Cycle tRWC RAS tRAS VIH tRP VIL tCSH tCRP CAS tRAD VIL VIH VIL tCRP tRSH tCAS VIH tASR Address tRCD tRAH Row tCWL tRWL tCAH tASC Column tCWD tRCS tRWD WE OE tWP VIH VIL tAWD tAA tOEH tOEA VIH tOED VIL tDH tCAC tRAC DQ VI/OH VI/OL tOEZ tCLZ Valid Data-out tDS Valid Data-in “H” or “L” 11/16 FEDD5117805F-01 1Semiconductor MSM5117805F Fast Page Mode Read Cycle (Part-1) tRASP RAS VIH VIL Address tHPC tCSH tCRP CAS VIH VIL tRAD tASR tASC tRAH Row tRHCP tCP tCP tCAS VIH VIL tRP tRCD tCAS tCAH tASC Column tCAS tASC tCAH Column tCAH Column tRCS WE OE tOCH VIH tAA VIL tCAC tRAC tAA VIH VIL tCAC tOEP tOEA tOEA tOEZ tOEZ tDOH VOH Valid Data-out VOL tCAC tAA tCHO tOEP tCPA tOEA DQ tRRH Valid Data-out Valid * Data-out tREZ Valid * Data-out tCLZ * : Same Data, “H” or “L” Fast Page Mode Read Cycle (Part-2) tRP tRASP RAS VIH VIL tCRP tCSH Address VIH VIL tCAS tCAS tASR tRAD tRAH Row tASC tCAH OE tCAH tASC Column Column tRCS WE tCP tCP VIH VIL tCRP tHPC tRCD CAS tRHCP tHPC tCAS tASC tCAH Column tRCS VIH VIL tAA tRAC tRCH tWPE tOEA VIH tAA tCPA tAA tCAC tDOH VIL tCAC tCAC DQ VOH VOL tWEZ Valid Data-out Valid Data-out tCEZ Valid Data-out tCLZ “H” or “L” 12/16 FEDD5117805F-01 1Semiconductor MSM5117805F Fast Page Mode Write Cycle (Early Write) tRP tRASP RAS CAS Address WE OE tCSH VIH VIL tCRP tHPC tRCD tCP VIH VIL tRAD tASR tASC tRAH Row tASC Column tWCS VIH tRSH tCAS tCAS tCAH tASC tCAH Column tWCS tWCH tCAH Column tWCS tWCH tWCH VIL VIH VIL tDS DQ tCP tCAS VIH VIL tHPC VIH tDH tDS Valid Data-in VIL tDH tDS tDH Valid Data-in Valid Data-in “H” or “L” Fast Page Mode Read Modify Write Cycle tRASP RAS CAS VIH VIL tRWD tCRP tRCD tCP VIH VIL VIH VIL tASC tASC tRAD tHPRWC tRAH Row Column VIH VIL Column VIH tAWD tAWD tAA tDS tAA tOED VI/OH tCLZ tDS tWP tOEA VIL VI/OL tWP tOEA tCAC DQ tCWD tRCS tRAC OE tCAH tCPA tCWL tCAH tRCS WE tRWL tCWD tASR Address tCPWD tOED tOEH tOEZ tDH Valid Data-out Valid Data-in tCAC tOEH tOEZ Valid Data-out tDH Valid Data-in tCLZ “H” or “L” 13/16 FEDD5117805F-01 1Semiconductor MSM5117805F RAS-only Refresh Cycle RAS tRC RAS CAS Address tRAS VIH VIL tRP tRPC tCRP VIH VIL tASR VIH tRAH Row VIL tCEZ DQ VOH Open VOL Note: WE, OE = “H” or “L” “H” or “L” CAS before RAS Refresh Cycle tRP RAS CAS WE tRC tRAS VIH VIL tRPC tCP tRP tCSR tRPC tCHR VIH VIL tWRP tWRH tWRP VIH VIL tCEZ DQ VOH VOL Open Note: OE, Address = “H” or “L” “H” or “L” 14/16 FEDD5117805F-01 1Semiconductor MSM5117805F Hidden Refresh Read Cycle tRC RAS CAS VIH VIL tCRP tRAS tRCD tRSH tRAD VIL tRAH VIH tASC Row VIL tCAH Column tCAC VIH VIL DQ tRRH tRAL tREZ tAA tROH OE tRP VIH tRCS WE tRP tCHR tASR Address tRC tRAS tWRP tWRH tCEZ tOEA VIH VIL tRAC tOEZ tCLZ VOH Open VOL Valid Data-out “H” or “L” Hidden Refresh Write Cycle tRC RAS CAS VIH VIL tCRP WE tRCD DQ tRSH tRP tRP tCHR tRAD VIL VIH VIL tRAH tASC Row tCAH Column tRAL tRWL tWP VIH VIL tWCS OE tRAS VIH tASR Address tRC tRAS tWCH tWRP tWRH VIH VIL VIH tDS tDH Valid Data-in VIL “H” or “L” 15/16 FEDD5117805F-01 1Semiconductor MSM5117805F NOTICE 1.
