8M x 32 DRAM SIMM using 4Mx4, 4K/2K Refresh, 5V
GENERAL DESCRIPTION
FEATURES
The Samsung KMM53280(1)00CK is a 8Mx32bits Dynamic
RAM high density memory module. The Samsung
KMM53280(1)00CK consists of sixteen CMOS 4Mx4bits
DRAMs in 24-pin SOJ package mounted 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
KMM53280(1)00CK 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. 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.
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.
3. Measured with a load equivalent to 2 TTL loads and 100pF.
9. These parameter are referenced to the CAS leading edge in
early write cycles.
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 .
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.
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 VOH or
VOL.
