GENERAL DESCRIPTION
FEATURES
• Part Identification
Part number
The Samsung M374F160(8)0BJ1-C is a 16Mx72bits Dynamic
RAM high density memory module. The Samsung
M374F160(8)0BJ1-C consists of eighteen CMOS 16Mx4bits
DRAMs in SOJ 400mil packages and one 1K/2K EEPROM for
SPD in 8-pin SOP package mounted on a 168-pin glass-
epoxy substrate. A 0.1 or 0.22uF decoupling capacitor is
mounted on the printed circuit board for each DRAM. The
M374F160(8)0BJ1-C is a Dual In-line Memory Module and is
intended for mounting into 168 pin edge connector sockets.

NOTES
1.
2.
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.
8.
Either tRCH or tRRH must be satisfied for a read cycle.
9. Operation within the tRAD(max) limit insures that tRAC(max)
can be met. tRAD(max) is specified as a reference point only.
If tRAD is greater than the specified tRAD(max) limit, then
access time is controlled exclusively by tAA.
Input voltage levels are Vih/Vil. VIH(min) and VIL(max) are ref-
erence 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.
10.
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.
3. Measured with a load equivalent to 1 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.
11.
tASC³ 6ns.
5. Assumes that tRCD³ 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.
tWCS, tRWD, tCWD and tAWD are non-restrictive operating
parameter. They are inclueded in the data sheet as electrical
characteristics only. If tWCS³ tWCS(min), the cycle is an early
write cycle and the data out pin will remain high impedance
for the duration of the cycle. If tCWD³ tCWD(min),
tRWD³ tRWD(min) and tAWD³ tAWD(min), then the cycle is a
read-write cycle and the data output will contain the data
read from the selected address. If neither of the above conti-
tions are satisfied, The condition of the data out is indeterni-
mated.
