GENERAL DESCRIPTION
FEATURES
The Samsung KMM5362203C2W is a 2Mx36bits Dynamic
RAM high density memory module. The Samsung
KMM5362203C2W consists of four CMOS 1Mx16bits DRAMs
in 42-pin SOJ package mounted and two CMOS 1Mx4bit
Quad CAS DRAM in 24-pin SOJ package on a 72-pin glassepoxy substrate. A 0.1 or 0.22uF decoupling capacitor is
mounted on the printed circuit board for each DRAM. The
KMM5362203C2W is a Single In-line Memory Module with
edge connections and is intended for mounting into 72 pin
edge connector sockets.

NOTES
7. tWCS is non-restrictive operating parameter. It is included in
the data sheet as electrical characteristic s 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.
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. VIH(min) and V IL(max) are reference levels for measuring
timing of input signals. Transition times are measured
between V IH(min) and V IL(max) and are assumed to be 5ns
for all inputs.
8. Either tRCH or tRRH must be satisfied for a read cycle.
9. These parameter are referenced to the CAS leading edge in
early write cycles.
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 condition and is not referenced to V OH or
VOL .
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 .
11. In order to hold the address latched by the first CAS going
low, the parameter tCLCH must be met.
