GENERAL DESCRIPTION
FEATURES
The Samsung KMM5328004C is a 8Mx32bits Dynamic RAM
high density memory module. The Samsung KMM5328004C
consists of four CMOS 4Mx16bits DRAMs in TSOP packages
mounted on a 72-pin glass-epoxy substrate. A 0.1 or 0.22uF
decoupling capacitor is mounted on the printed circuit board
for each DRAM. The KMM5328004C is a Single In-line Memory Module with edge connections and is intended for mounting into 72 pin edge connector sockets.

NOTES
1. 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.
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 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 tRCD≥tRCD(max).
6. This parameter defines the time at which the output achieves
the open circuit and is not referenced for VOH or VOL.
7. tWCS is non-restrictive operating parameter. It is included in
the data sheet as electrical characteristics only. If
tWCS≥tWCS (min), the cycle is an early write cycle and the
data out pin will remain high impedance for the duration of
the cycle.
8. Either tRCH or tRRH must be satisfied for a read cycle.
9. These parameters are referenced to the CAS leading edge in
early write cycles.
10. Operation within the tRAD(max) limit insures that tRAC(max)
can be met. tRAD(max) is specified as reference point only. If
tRAD is greater than the specified tRAD(max) limit access time
is controlled by tAA.
11. tASC≥6ns, Assume tT=2.0ns.
12. If RAS goes high before CAS high going, the open circuit
condition of the output is achieved by CAS high going. If CAS
goes high before RAS high going , the open circuit condition
of the output is achieved by RAS going.
