M53620400DW0/DB0 & M53620410DW0/DB0 with Fast Page Mode
4M x 36 DRAM SIMM using 4Mx4 and 16M Quad CAS, 4K/2K Refresh, 5V
GENERAL DESCRIPTION
The Samsung M5362040(1)0D is a 4Mx36bits Dynamic RAM
high density memory module. The Samsung M5362040(1)0D
consists of eight CMOS 4Mx4bits DRAMs in 24-pin SOJ pack-
age and one CMOS 4Mx4 bit Quad CAS 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 M5362040(1)0D 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.
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. In order to hold the address latched by the first CAS going
low, the parameter
t
CLCH
must be met.
