AC measurements assume t T = 2 ns. 2. An initial pause of 200 µs is required after power up followed by a minimum of eight initialization cycles (any combination of cycles containing RAS -only refresh or CAS -before-RAS refresh). If the internal refresh counter is used, a minimum of eight CAS -before-RAS refresh cycles are required. 3. Operation with the t RCD (max) limit insures that t RAC (max) can be met, t RCD (max) is specified as a reference point only; if t RCD is greater than the specified t RCD (max) limit, then access time is controlled exclusively by t CAC . 4. Operation with the t RAD (max) limit insures that t RAC (max) can be met, t RAD (max) is specified as a reference point only; if t RAD is greater than the specified t RAD (max) limit, then access time is controlled exclusively by t AA . 5. Either t OED or t CDD must be satisfied. 6. Either t DZO or t DZC must be satisfied. 7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition times are measured between VIH (min) and VIL (max). 8. Assumes that t RCD ≤ t RCD (max) and t RAD ≤ t RAD (max). If t RCD or t RAD is greater than the maximum recommended value shown in this table, t RAC exceeds the value shown. 9. Measured with a load circuit equivalent to 1 TTL loads and 100 pF. 10. Assumes that t RCD ≥ t RCD (max) and t RAD ≤ t RAD (max). 11. Assumes that t RCD ≤ t RCD (max) and t RAD ≥ t RAD (max). 12. Either t RCH or t RRH must be satisfied for a read cycles. 13. t OFF (max) and t OEZ (max) define the time at which the outputs achieve the open circuit condition and are not referred to output voltage levels. 14. t WCS , t RWD, t CWD, t AWD and t CPW are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only; if t WCS ≥ t WCS (min), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if t RWD ≥ t RWD (min), t CWD ≥ t CWD (min), and t AWD ≥ t AWD (min), or t CWD ≥ t CWD (min), t AWD ≥ t AWD (min) and t CPW ≥ t CPW (min), the cycle is a read-modify-write and the data output 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. 15. These parameters are referred to CAS leading edge in early write cycles and to WE leading edge in delayed write or read-modify-write cycles. 16. t RASP defines RAS pulse width in EDO page mode cycles. 17. Access time is determined by the longest among t AA , t CAC and t CPA. 18. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. 19. t HPC (min) can be achieved during a series of EDO page mode write cycles or EDO page mode read cycles. If both write and read operation are mixed in a EDO page mode RAS cycle (EDO page mode mix cycle (1), (2)), minimum value of CAS cycle (tCAS + t CP + 2 t T) becomes greater than the specified t HPC (min) value. The value of CAS cycle time of mixed EDO page mode is shown in EDO page mode mix cycle (1) and (2). LP Data Sheet E0155H10 ro du ct HM51W17805 Series EO 20. Data output turns off and becomes high impedance from later rising edge of RAS and CAS . Hold time and turn off time are specified by the timing specifications of later rising edge of RAS and CAS between t OHR and t OH , and between t OFR and t OFF. 21. Please do not use t RASS timing, 10 µs ≤ t RASS ≤ 100 µs. During this period, the device is in transition state from normal operation mode to self refresh mode. If t RASS ≥ 100 µs, then RAS precharge time should use t RPS instead of t RP. 22. If you use RAS only refresh or CBR burst refresh mode in normal read/write cycles, 2048 cycles of distributed CBR refresh with 15.6 µs interval should be executed within 32 ms immediately after exiting from and before entering into the self refresh mode. 23. If you use distributed CBR refresh mode with 15.6 µs interval in normal read/write cycle, CBR refresh should be executed within 15.6 µs immediately after exiting from and before entering into self refresh mode. 24. Repetitive self refresh mode without refreshing all memory is not allowed. Once you exit from self refresh mode, all memory cells need to be refreshed before re-entering the self refresh mode again. 25.
