GENERAL DESCRIPTION
FEATURES
The Samsung KMM53216000C is a 16Mx32bits Dynamic
RAM high density memory module. The Samsung
KMM53216000C consists of eight CMOS 16Mx4bits DRAMs
in SOJ 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 KMM53216000C 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.
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 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.
3. Measured with a load equivalent to 2 TTL loads and 100pF.
8. Either tRCH or tRRH must be satisfied for a read cycle.
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).
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.
