KMM5324000BSW/BSWG Fast Page Mode
4M x 32 DRAM SIMM Using 4Mx16, 4K Refresh, 5V
GENERAL DESCRIPTION
The Samsung KMM5324000B is a 4Mx32bits Dynamic RAM
high density memory module. The Samsung KMM5324000B
consists of two 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 KMM5324000B is a Single In-line Mem-
ory Module with edge connections and is intended for mount-
ing 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.
6. This parameter defines the time at which the output achieves
the open circuit condition and is not referenced to VOH or
VOL.
2. Input voltage levels are Vih/Vil. VIH(min) and VIL(max) are ref-
erence levels for measuring timing of input signals. Transi-
tion 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 tRCDtRCD(max).
7. tWCS is non-restrictive operating parameter. It is included in
the data sheet as electrical characteristics only. If
tWCStWCS(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, then
access time is controlled by tAA.
