Pin Assignments and Descriptions
Table 6: Pin Descriptions
Symbol Type Description
A0–A14 Input
(SSTL_18) Address inputs: Provide the row address for ACTIVE commands and the column address, and
auto precharge bit (A10) for READ/WRITE commands, to select one location out of the memory
array in the respective bank. A10 sampled during a PRECHARGE command determines whether
the PRECHARGE applies to one device bank (A10 LOW , device bank selected by BA0–BA2) or all
device banks (A10 HIGH). The address inputs also provide the op-code during a LOAD MODE
command. A0–A13 (2GB) and A0–A14 (4GB).
BA0–BA2 Input
(SSTL_18) Bank address inputs: BA0–BA2 define to which device bank an ACTIVE, READ, WRITE, or
PRECHARGE comman d is being applie d. BA0–BA2 define which mode register, including MR ,
EMR, EMR(2) , an d EMR(3), is load ed during the LOAD MO D E com m a nd.
CK0, CK0#
CK1, CK1# Input
(SSTL_18) Clock: CK and CK# are differential clock inputs. All address and control input signals are
sampled on the crossing of the positive edge of CK and the negative edge of CK#. Output data
(DQ and DQS/DQS#) is referenced to the crossings of CK and CK#.
CKE0, CKE1 Input
(SSTL_18) Clock enable: CKE (registered HIGH) activates and CKE (registered LOW) deactivates clocking
circuitry on the DDR2 SDRAM.
DM0–DM7 Input
(SSTL_18) Data input mask: DM is an input mask signal for write data. Input data is masked when DM is
sampled HIGH along with that input data during a WRITE access. DM is sampled on both edges
of DQS. Although DM pins are input-only , the DM loading is designed to match that of DQ and
DQS pins.
ODT0, ODT1 Input
(SSTL_18) On-die termination: ODT (registered HIGH) enables termination resistance internal to the
DDR2 SDRAM. When enabled, ODT is only ap plied to each of the following pins : DQ, DQS,
DQS#, and DM. The ODT input will be ignored if disabled via the LOAD MODE command.
RAS#, CAS#,
WE# Input
(SSTL_18) Command inputs: RAS#, CAS#, and WE# (along with S#) define the command being entered.
S0#, S1# Input
(SSTL_18) Chip select: S# enables (registered LOW) and disables (registered HIGH) the command
decoder. All commands are masked when S# is registered HIGH. S# provides for external rank
selection on systems with multiple ranks. S# is considered part of the command code.
SA0–SA1 Input
(SSTL_18) Presence-detect address inputs: These pins are used to configure the presence-det ect
devices.
SCL Input
(SSTL_18) Serial clock for prese nce- d etec t: SCL is used to synchronize the presence-detect data
transfer to and from the module.
DQ0–DQ63 I/O
(SSTL_18) Data input/output: Bidirectional data bus.
DQS0–DQS7,
DQS0#–DQS7# I/O
(SSTL_18) Data strobe: Output with read data, input with write data for source sync hronou s operation.
Edge-aligned with read data, center-aligned with write data. DQS# is on ly used when
differential data strobe mode is enabled via the LOAD MODE command.
SDA I/O
(SSTL_18) Serial presence-detect data: SDA is a bidirectional pin used to transfer addresses and data
into and out of the presence-detect portion of the module.
VDD Supply Power supply: +1.8 ±0.1V.
VDDSPD Supply Serial EEPROM positive power supply: +1.7V to +3.6V.
VREF Supply SSTL_18 reference voltage (VDD/2).
VSS Supply Ground.
NC No connect: These pins are not connected on the module.

2GB, 4GB (x64, DR) 200-Pin DDR2 SDRAM SODIMM
General Description
General Description
The MT16HTS25664H and MT16HTS51264H DDR2 SDRAM modules are high-speed,
CMOS, dynamic random access 2GB and 4GB memory modules organized in a x64 con-
figuration. These modules use 2Gb and 4Gb TwinDie DDR2 SDRAM devices with eight
internal ban ks.
DDR2 SDRAM modules use double data ra te architecture to achieve high-speed opera-
tion. The double data rate archi t ecture is essentially a 4n-prefetch architecture with an
interface designed to transfer two data words per clock cycle at the I/O pins. A single
read or write access for the DDR2 SDRAM module effectively consis ts of a single 4n-bit-
wide, one-clock-cycle data transfer at the internal DRAM core and four corresponding
n-bit-wide, one-half-clock-cycle data transfers at the I/O pins.
A bidirectional data strobe (DQS, DQS#) i s transmitted externally, along with data, for
use in data capture at the receiver. DQS is a strobe transmitted by the DDR2 SDRAM
device during READs and by the memory controller during WRITEs. DQS is edge-
aligned with data for READs and center-aligned with data for WRITEs.
DDR2 SDRAM modul es operate from a differential clock (CK and CK#); the crossing of
CK going HIGH and CK# going LOW will be referred to as the positive edge of CK. Com-
mands are registered at every positive edge of CK . Input data is registered on both edges
of DQS, and output data is referenced to both edges of DQS, as well as to both edges of
CK.
Serial Presence-Detect Operation
DDR2 SDRAM modules incorporate seri al presence-d etect (SPD). The SPD functio n is
implemented using a 2048-bit EEPROM. This nonvolatile storage device contains
256 bytes . The first 128 b ytes are pr ogrammed b y Micron to identify the module type and
various SDRAM organizations and timing parameters. The remaining 128 bytes of stor-
age are available for use by the customer. System READ/WRITE operations between the
master (system logic) and the slave EEPROM device occur via a standard I2C bus using
the DIMM’s SCL (clock) and SDA (data) signals, together with SA (1:0), which provide
four unique DIMM/EEPROM addresses. Write protect (WP) is pulled down to VSS on the
module, permanently disabling hardware write protect.

Electrical Specifications
Electrical Specifications
S tresses greater than those listed in Table 7 may cause permanent damage to the mod-
ule. This is a stress rating only, and functional operation of the module at these or any
other conditions outside those ind icated on the device data shee t is not impl ie d . Expo -
sure to absolute maximum rating conditions for extended periods may adversely affect
reliability.
Notes: 1. The refresh rate is required to double when 85°C < TC 95°C.
2. For fur th e r informatio n, r ef er to technical note TN-00-08: “Thermal Applications,” avail-
able on Micron’s W eb site.
Input Capacitance
Micron encourages designers to simulate the performance of the module to achieve
optimum values. Simulations are sign ificantly mor e accurate and realistic than a gr oss
estimation of module capacitance when inductance and delay parameters associated
with trace lengths are used in simulations. JEDEC modules are currently designed using
simulations to cl ose timing budget s.
AC Timing and Operating Conditions
Re commended AC operating conditions are given in the DDR2 component data sheets.

correlate with component speed grades, as shown in Table 8.

Serial Presence-Detect
Serial Presence-Detect
Notes: 1. To avoid spurious st art and stop conditions, a minimum delay is plac ed between SCL = 1
and the falling or rising edge of SDA.
2. This parameter is sampled.
3. For a restart condition or following a WRITE cycle.
4. The SPD EEPROM WRITE cycle time (tWRC) is the time from a valid stop condition of a
write sequence to the end of the EEPROM internal ERASE/PROGRAM cycle. During the
WRITE cycle, the EEPROM bus interface circuit is disabled, SDA remains HIGH due to pull-
up resista nce, and the E EP R O M does not res pond to its sla v e ad dress.
