CMOS DRAM
1M x 16Bit CMOS Dynamic RAM with Fast Page Mode
DESCRIPTION
This is a family of 1,048,576 x 16 bit Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access of memory cells within the same row. Power supply voltage (+5.0V or +3.3V), refresh cycle (1K Ref. or 4K Ref.), access time (-50 or -60), power consumption(Normal or Low power) and package type(SOJ or TSOP-II) are optional features of this family. All of this family have CASbefore-RAS refresh, RAS-only refresh and Hidden refresh capabilities. Furthermore, Self-refresh operation is available in L-version. This 1Mx16 Fast Page Mode DRAM family is fabricated using Samsungs advanced CMOS process to realize high band-width, low power consumption and high reliability. It may be used as graphic memory unit for microcomputer, personal computer and portable machines.

NOTES
CMOS DRAM
1. An initial pause of 200us is required after power-up followed by any 8 RAS-only refresh or CAS-before-RAS refresh cycles before proper device operation is achieved. 2. Input voltage levels are Vih/Vil. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Transition times are measured between VIH(min) and VIL(max) and are assumed to be 5ns for all inputs. 3. Measured with a load equivalent to 2 TTL(5V)/1TTL(3.3V) loads and 100pF. 4. Operation within the tRCD(max) limit insures 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 access time is controlled exclusively by tCAC. 5. Assumes that tRCDtRCD(max). 6. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to Voh or Vol. 7. tWCS, tRWD, tCWD, tAWD and tCPWD are non restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCStWCS(min), the cycle is an early write cycle and the data output will remain high impedance for the duration of the cycle. If tCWDtCWD(min), tRWDtRWD(min), tAWDtAWD(min) and tCPWDtCPWD(min), then the cycle is a readmodify-write cycle and the data output will contain the data read from the selected address. If neither of the above conditions is satisfied, the condition of the data out is indeterminate. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. These parameters are referenced to CAS falling edge in early write cycles and to W falling edge in OE controlled write cycle and read-modify-write cycles. 10. Operation within the tRAD(max) limit insures 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 access time is controlled by tAA. 11. tASC, tCAH are referenced to the earlier CAS falling edge. 12. tCP is specified from the later CAS rising edge in the previous cycle to the earlier CAS falling edge in the next cycle.

13. tCWD is referenced to the later CAS falling edge at word read-modify-write cycle. 14. tCWL is specified from W falling edge to the earlier CAS rising edge. 15. tCSR is referenced to the earlier CAS falling edge before RAS transition low. 16. tCHR is referenced to the later CAS rising edge after RAS transition low.

17. tDS, tDH is independently specified for lower byte DQ(0-7), upper byte DQ(8-15) 18. If tRASS100us, then RAS precharge time must use tRPS instead of tRP. 19. For RAS-only refresh and burst CAS-before-RAS refresh mode, 4096(4K)/1024(1K) cycles of burst refresh must be executed within 64ms/16ms before and after self refresh, in order to meet refresh specification. 20. For distributed CAS-before-RAS with 15.6us interval CAS-before-RAS refresh should be executed with in 15.6us immediately before and after self refresh in order to meet refresh specification.
