KMM5364105CK/CKG
KMM5364005CK/CKG & KMM5364105CK/CKG Fast Page Mode with EDO Mode
4M x 36 DRAM SIMM using 4Mx4 and 16M Quad CAS, 4K/2K, Refresh, 5V
GENERAL DESCRIPTION
The Samsung KMM53640(1)05CK is a 4Mx36bits Dynamic
RAM high density memory module. The Samsung
KMM53640(1)05CK consists of eight CMOS 4Mx4bits DRAMs
in 24-pin SOJ package and one CMOS 4Mx4 bit Quad CAS
with EDO DRAM in 28-pin SOJ package 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
KMM53640(1)05CK 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. V
IH
(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.
3. Measured with a load equivalent to 2 TTL loads and 100pF.
4. Operation within the
t
RCD
(max) limit insures that
t
RAC
(max)
can be met.
t
RCD
(max) is specified as a reference point only.
If
t
RCD
is greater than the specified
t
RCD
(max) limit, then
access time is controlled exclusively by
t
CAC
.
5. Assumes that
t
RCD
≥
t
RCD
(max).
6. This parameter defines the time at which the output achieves
the open circuit condition and is not referenced to V
OH
or
V
OL
.
7.
t
WCS
is non-restrictive operating parameter. It is included in
the data sheet as electrical characteristics only. If
t
WCS
≥
t
WCS
(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
t
RCH
or
t
RRH
must be satisfied for a read cycle.
9. These parameter are referenced to the CAS leading edge in
early write cycles and to the W leading edge in read-write
cycles.
10. Operation within the
t
RAD
(max) limit insures that
t
RAC
(max)
can be met.
t
RAD
(max) is specified as reference point only. If
t
RAD
is greater than the specified
t
RAD
(max) limit, then
access time is controlled by
t
AA
.
11.
t
CEZ
(max),
t
REZ
(max),
t
WEZ
(max) and
t
OEZ
(max) define the
time at which the output achieves the open circuit condition
and are not referenced to output voltage level.
12. If RAS goes to high before CAS high going, the open circuit
condtion of the output is achieved by CAS high going. If CAS
goes to high before RAS high going, the open circuit cond-
tion of the output is achieved by RAS high going.
13.
t
ASC
≥
t
CP
min
14. In order to hold the address latched by the first CAS going
low, the parameter
t
CLCH
must be met.
