184pin Unbuffered DDR SDRAM MODULE
M368L6423CTL DDR SDRAM 184pin DIMM
64Mx64 DDR SDRAM 184pin DIMM based on 32Mx8
GENERAL DESCRIPTION
The Samsung M368L6423CTL is 32M bit x 64 Double Data
Rate SDRAM high density memory module. The Samsung
M368L6423CTL consists of sixteen CMOS 32M x 8 bit with
4banks Double Data Rate SDRAMs in 66pin TSOP-II(400mil)
packages mounted on a 184pin glass-epoxy substrate. Four
0.1uF decoupling capacitors are mounted on the printed circuit
board in parallel for each DDR SDRAM. The M368L6423CTL
Dual In-line Memory Module and is intended for mounting into
184pin edge connector sockets.
Synchronous design allows precise cycle control with the use
of system clock. I/O transactions are possible on every clock
cycle. Range of operating frequencies, programmable laten-
cies and burst lengths allows the same device to be useful for a
variety of high bandwidth, high performance memory system
applications.

Notes
1. Includes
±
25mV margin for DC offset on V
REF
, and a combined total of
±
50mV margin for all AC noise and DC offset on V
REF
,
bandwidth limited to 20MHz. The DRAM must accommodate DRAM current spikes on V
REF
and internal DRAM noise coupled
TO V
REF
, both of which may result in V
REF
noise. V
REF
should be de-coupled with an inductance of
≤
3nH.
2.V
TT
is not applied directly to the device. V
T T
is a system supply for signal termination resistors, is expected to be set equal to
V
REF
, and must track variations in the DC level of V
REF
3. V
I D
is the magnitude of the difference between the input level on CK and the input level on CK.
4. These parameters should be tested at the pin on actual components and may be checked at either the pin or the pad in
simulation. The AC and DC input specifications are relative to a VREF envelop that has been bandwidth limited to 200MHZ.
5. The value of V
IX
is expected to equal 0.5*V
DDQ
of the transmitting device and must track variations in the dc level of the same.
6. These charactericteristics obey the SSTL-2 class II standards.
