KM416V4004C,KM416V4104C CMOS DRAM
This is a family of 4,194,304 x 16 bit Extended Data Out Mode CMOS DRAMs. Extended Data Out Mode offers high speed random access of memory cells within the same row. Refresh cycle(4K Ref. or 8K Ref.), access time (-45, -5 or -6), power consumption(Normal or Low power) are optional features of this family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. Furthermore, Self-refresh operation is available in L-version. This 4Mx16 EDO Mode DRAM family is fabricated using Sam­sungs advanced CMOS process to realize high band-width, low power consumption and high reliability.

NOTES
An initial pause of 200us is required after power-up followed by any 8 RAS-only or CAS-before-RAS refresh cycles before proper device operation is achieved. 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 2ns for all inputs. Measured with a load equivalent to 1 TTL load and 100pF. 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. Assumes that tRCDtRCD(max). This parameter defines the time at which the output achieves the open circuit condition and is not referenced to Voh or Vol.
tWCS, tRWD, tCWD and tAWD are non restrictive operating parameters. They are included in the data sheet as electric charac-
teristics only. If tWCStWCS(min), the cycles is an early write cycle and the data output will remain high impedance for the duration of the cycle. If tCWDtCWD(min), tRWDtRWD(min) and tAWDtAWD(min), then the cycle is a read-modify-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. Either tRCH or tRRH must be satisfied for a read cycle. This parameters are referenced to the CAS leading edge in early write cycles and to the W falling edge in OE controlled write cycle and read-modify-write cycles. 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.
These specifiecations are applied in the test mode. In test mode read cycle, the value of tRAC, tAA, tCAC is delayed by 2ns to 5ns for the specified values. These parameters should be specified in test mode cycles by adding the above value to the specified value in this data sheet.
tASC, tCAH are referenced to the earlier CAS falling edge. tCP is specified from the last CAS rising edge in the previous cycle to the first CAS falling edge in the next cycle. tCWD is referenced to the later CAS falling edge at word read-modify-write cycle.

tCWL is specified from W falling edge to the earlier CAS rising edge. tCSR is referenced to earlier CAS falling before RAS transition low. tCHR is referenced to the later CAS rising high after RAS transition low.
tDS is specified for the earlier CAS falling edge and tDH is specified by the later CAS falling edge in early write cycle.
If RAS goes high before CAS high going, the open circuit condition of the output is achieved by CAS high going.
tASC≥6ns, Assume tT=2.0ns, if tASC≤6ns, then tHPC(min) and tCAS(min) must be increased by the value of "6ns-tASC".
If tRASS100us, then RAS precharge time must use tRPS instead of tRP. For RAS-only-Refresh and Burst CAS-before-RAS refresh mode, 4096 cycles(4K/8K) of burst refresh must be executed within 64ms before and after self refresh, in order to meet refresh specification. For distributed CAS-before-RAS with 15.6us interval, CBR refresh should be executed with in 15.6us immediately before and after self refresh in order to meet refresh specification.
