GENERAL DESCRIPTION
FEATURES
• Part Identification
Part number
The Samsung M372C320(8)0CJ0-C is a 32Mx72bits Dynamic
RAM high density memory module. The Samsung
M372C320(8)0CJ0-C consists of thirty-six CMOS 16Mx4bits
DRAMs in SOJ 400mil packages and two 16 bits driver IC in
TSSOP package mounted on a 168-pin glass-epoxy sub-
strate. A 0.1 or 0.22uF decoupling capacitor is mounted on
the printed circuit board for each DRAM. The
M372C320(8)0CJ0-C is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.

PD Note :PD & ID Terminals must each be pulled up through a resistor to VCC at the next higher
level assembly. PDs will be either open (NC) or driven to VSS via on-board buffer circuits.
ID Note : IDs will be either open (NC) or connected directly to VSS without a buffer.
PD : 0 for Vol of Drive IC & 1 for N.C

NOTES
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.
7.
1.
tWCS, tRWD, tCWD, tAWD and tCPWD are not restrictive operat-
ing parameter. They are included in the data sheet as electri-
cal characteristics only. If tWCS³ tWCS(min) the cycle is an
early write cycle and the data out pin will remain high imped-
ance for the duration of the cycle. If tRWD³ tRWD(min),
tCWD³ tCWD(min), tAWD³ tAWD(min) and tCPWD³ tCPWD(min).
The cycle is a read-modify-write cycle and the data out will
contain data read from the selected cell. If neither of the
above sets of conditions is satisfied, the condition of data
out(at access time) is indeterminate.
2. Input voltage levels are Vih/Vil. VIH(min) and VIL(max) are ref-
erence levels for measuring timing of input signals. Transi-
tion times are measured between VIH(min) and VIL(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 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.
8. Either tRCH or tRRH must be satisfied for a read cycle.
9.
These parameters are referenced to the CAS leading edge in
early write cycles.
5.
6.
Assumes that tRCD³ tRCD(max).
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.
This parameter defines the time at which the output achieves
the open circuit condition and is not referenced to VOH or
VOL.
11.
The timing skew from the DRAM to the DIMM resulted from
the addition of buffers.
