4,194,304-word x 1-bit Dynamic RAM
ADE-203-680 (Z) Preliminary Rev. 0.0 Dec. 3, 1996 Description
The Hitachi HM514100D is a CMOS dynamic RAM organized 4,194,304 word x 1-bit. HM514100D has realized higher density, higher performance and various functions by employing 0.8 m CMOS process technology and some new CMOS circuit design technologies. The HM514100D offers Fast Page Mode as a high speed access mode. Multiplexed address input permits the HM514100D to be packaged in standard 300-mil 26-pin plastic SOJ and 26-pin plastic TSOP II.
Features

HM514100D Series
Notes: 1. AC measurements assume t T = 5 ns. 2. 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. 3. Measured with a load circuit equivalent to 2 TTL loads and 100 pF. 4. Assumes that t RCD tRCD (max) and tRAD tRAD (max). 5. Assumes that t RCD tRCD (max) and tRAD tRAD (max). 6. t OFF (max) defines the time at which the output achieves the open circuit condition and is not referred to output voltage levels. 7. VIH (min) and VIL (max) are reference levels for measuring timing of input signals. Also, transition times are measured between V IH and VIL. 8. 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 . 9. 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 . 10. t WCS , t RWD, t CWD, t AWD and tCPW 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), 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. 11. These parameters are referred to CAS leading edge in an early write cycle and to WE leading edge in a delayed write or read-modify-write cycle. 12. An initial pause of 100 s is required after power up followed by a minimum of eight initializa-tion cycles (RAS-only refresh cycle or CAS-before-RAS refresh cycle). If the internal refresh counter is used, a minimum of eight CAS-before-RAS refresh cycles is required. 13. t RASC defines RAS pulse width in fast page mode cycles. 14. Access time is determined by the longest among t AA , t CAC and t ACP. 15. Test mode operation specified in this data sheet is 8-bit test function controlled by control address bits - - - RA10, CA10 and CA0. This test mode operation can be performed by WE-and-CASbefore-RAS (WCBR) refresh cycle. Refresh during test mode operation will be performed by normal read cycles or by WCBR refresh cycles. When the state of eight test bits accord each other, the condition of the output data is high level. When the state of test bits do not accord, the condition of the output data is low level. Data output pin is Dout and data input pin is Din. In order to end this test mode operation, perform a CAS-before-RAS refresh cycle or a RAS-only refresh cycle. 16. In a test mode read cycle, the value of tRAC , t AA , t CAC and t ACP is delayed for 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. 17. Either t RCH or tRRH must be satisfied 18. t RAS (min) = tRWD (min) + tRWL (min) + tT in read-modify-write cycle. 19. t CAS (min) = tCWD (min) + tCWL (min) + tT in read-modify-write cycle. 20. XXX: H or L (H: VIH (min) VIN VIH (max), L: VIL (min) VIN VIL (max)) ///////: Invalid Dout When the address, clock and input pins are not described on timing waveforms, their pins must be applied V IH or VIL.
