M470L3224BT0 200pin DDR SDRAM SODIMM
32Mx64 200pin DDR SDRAM SODIMM based on 16Mx16
The Samsung M470L3224BT0 is 32M bit x 64 Double Data
Rate SDRAM high density memory modules based on first gen
of 256Mb DDR SDRAM respectively.
The Samsung M470L3224BT0 consists of eight CMOS 16M x
16 bit with 4banks Double Data Rate SDRAMs in 66pin TSOP-
II(400mil) packages mounted on a 200pin glass-epoxy sub-
strate. Four 0.1uF decoupling capacitors are mounted on the
printed circuit board in parallel for each DDR SDRAM.
The M470L3224BT0 is Dual In-line Memory Modules and
intended for mounting into 200pin edge connector sockets.
Synchronous design allows precise cycle control with the use
of system clock. Data I/O transactions are possible on both
edges of DQS. Range of operating frequencies, programmable
latencies and burst lengths allow the same device to be useful
for a variety of high bandwidth, high performance memory sys-
tem applications.

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.
Functional operation should be restricted to recommended operating condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.
Note :
POWER & DC OPERATING CONDITIONS (SSTL_2 In/Out)
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
TT
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
ID
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.
