Notes ct du ro Notes: 1. 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 tRCD (max) limit insures that tRAC (max) can be met, tRCD (max) is specified as a reference point only; if t RCD is greater than the specified tRCD (max) limit, then access time is controlled exclusively by tCAC . 4. Operation with the tRAD (max) limit insures that tRAC (max) can be met, tRAD (max) is specified as a reference point only; if t RAD is greater than the specified tRAD (max) limit, then access time is controlled exclusively by tAA . 5. Either t OED or tCDD must be satisfied. 6. Either t DZO or tDZC must be satisfied. 7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition times are measured between V IH (min) and VIL (max). 8. Assumes that t RCD ≤ tRCD (max) and tRAD ≤ tRAD (max). If tRCD or tRAD 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 ≥ tRCD (max) and tRCD + tCAC (max) ≥ tRAD + tAA (max). 11. Assumes that t RAD ≥ tRAD (max) and tRCD + tCAC (max) ≤ tRAD + tAA (max). 12. Either t RCH or tRRH must be satisfied for a read cycles. 13. t OFF (max) and tOEZ (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 ≥ tWCS (min), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle; if tRWD ≥ tRWD (min), tCWD ≥ tCWD (min), and tAWD ≥ tAWD (min), or tCWD ≥ tCWD (min), tAWD ≥ tAWD (min) and tCPW ≥ 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. Data Sheet E0152H10 15 EO HM51W16405 Series, HM51W17405 Series ct du ro LP 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 device. 19. The 16M DRAM offers a 16-bit time saving parallel test mode. Address CA0 and CA1 for the 4M ×4 are don’t care during test mode. Test mode is set by performing a WE-and-CAS-before-RAS (WCBR) cycle. In 16-bit parallel test mode, data is written into 4 bits in parallel at each I/O (I/O1 to I/O4) and read out from each I/O. If 4 bits of each I/O are equal (all 1s or 0s), data output pin is a high state during test mode read cycle, then the device has passed. If they are not equal, data output pin is a low state, then the device has failed. Refresh during test mode operation can be performed by normal read cycles or by WCBR refresh cycles. To get out of test mode and enter a normal operation mode, perform either a regular CASbefore-RAS refresh cycle or RAS-only refresh cycle. 20. In a test mode read cycle, the value of tRAC , t AA , t CAC and t CPA is delayed by 2 ns to 5 ns for the specified value. These parameters should be specified in test mode cycles by adding theabove value to the specified value in this data sheet. 21. 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 + tCP + 2 tT) 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). 22. 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. 23. Please do not use tRASS timing, 10 µs ≤ tRASS ≤ 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 tRPS instead of tRP. 24. 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. 25. If you use RAS only refresh or CBR burst refresh mode in normal read/write cycle, 4096 or 2048 cycles (4096 cycles: HM51W16405 Series, 2048 cycles: HM51W17405 Series) of distributed CBR refresh with 15.6 µs interval should be executed within 64 or 32 ms (64 ms: HM51W16405 Series, 32 ms: HM51W17405 Series) immediately after exiting from and before entering into the self refresh mode. 26. Repetitive self refresh mode without refreshing all memory is not allowed. Once you exit from self fresh mode, all memory cells need to be refreshed before re-entering the self refresh mode again. 27.
