Notes: 1. AC measurements assume t T = 5 ns. 2. An initial pause of 200 s 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. Only row address is indispensable on address A10 and A11. 4. 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 . 5. 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 . 6. Either t OED or tCDD must be satisfied. 7. Either t DZO or tDZC must be satisfied. 8. 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). 9. 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.

HM5116400B Series
10. Measured with a load circuit equivalent to 2 TTL loads and 100 pF. 11. Assumes that t RCD tRCD (max) and tRCD + tCAC (max) tRAD + tAA (max). 12. Assumes that t RAD tRAD (max) and tRCD + tCAC (max) tRAD + tAA (max). 13. Either t RCH or tRRH must be satisfied for a read cycles. 14. 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. 15. 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 t RWD tRWD (min), tCWD tCWD (min), and tAWD tAWD (min), or tCWD tCWD (min), tAWD tAWD (min) and tCPW tCPW (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. 16. 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. 17. t RASP defines RAS pulse width in fast page mode cycles. 18. Access time is determined by the longest among t AA , t CAC and t CPA. 19. In delayed write or read-modify-write cycles, OE must disable output buffer prior to applying data to the device. After RAS is reset, if tOEH tCWL, the I/O pin will remain open circuit (high impedance); if tOEH < tCWL, invalid data will be out at each I/O. 20. The 16M DRAM offers a 16-bit time saving parallel test mode. Address CA0 and CA1 for the 4M x 4 are don't care during test mode. Test mode is set by performing a WE-and-CAS-before-RAS (WCBR) cycle. In 16-bits 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 CAS-beforeRAS refresh cycle or RAS-only refresh cycle. 21. 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 the above value to the specified value in this data sheet. 22.
