Pin Assignments and Descriptions

Table 7: Pin Descriptions

Symbol Type Description

A0–A12 Input Address inputs: Provide the row address for ACTIVE commands, and the

column address and auto precharge bi t (A10) for READ/WRITE commands, to

select one location out of th e memory ar ray in the respe ctive device bank. A10

sampled during a PRECHARGE command determines whether the PRECHARGE

applies to one device bank (A10 LOW, device bank selected by BA0, BA1) or all

device banks (A10 HIGH). The address inputs also provide the op-code during a

MODE REGISTER SET comma nd. BA0 and BA1 define which mode register

(mode register or extended mode register) is loaded during the LOAD MODE

BA0, BA1 Input Bank address: BA0 and BA1 defi ne the device bank to which an ACTIVE,

READ, WRITE, or PRECHARGE command is being applied.

CK0, CK0#,

CK1, CK1#

CK2, CK2#

Input Clock: CK and CK# are differential clock inputs. All control, comman d, and

address input signals are sampled on the crossing of the positive edge of CK

and the negative edge of CK#. Ou tput d ata (DQ and DQS) is referenced to the

crossings of CK and CK#.

CKE0 Input Clock enable: CKE enables (registered HIGH) and disables (registere d LOW)

the internal clock, input buffers, and output dr ivers.

DM0–DM8 Input Input data mask: DM is an input mask signal for write data. Input data is

masked when DM is sampled HIGH, along with that input data, du ring 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 the DQ and DQS pins.

RAS#, CAS#, WE# Input Command inputs: RAS#, CAS#, and WE# (along with S#) define the command

being entered.

S0# Input Chip selects: S# enables (registered LOW) and disables (registered HIGH) the

command decoder.

presence-detect device.

SCL Input Serial clock for presence-detect: SCL is used to synchronize the presence-

detect data transfer to and from the module.

CB0–CB7 I/O Check bits.

DQ0–DQ63 I/O Data input/output: Data bus.

DQS0–DQS8 I/O Data strobe: Output with read data. Edge-aligned with read data. Input with

write data. Center-aligned with write data . Used to capture dat a.

SDA I/O 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: +2.5V ±0.2V (-40B: +2.6V ±0.1V).

VDDSPD Supply Serial EEPROM positive power supply: +2.3V to +3.6V.

128MB, 256MB, 512MB (x72, ECC, SR) 200-Pin DDR SDRAM SODIMM

General Description

The MT9VDDT1672H, MT9VDDT3272H, and MT9VDDT6472H are high-speed, CMOS

dynamic random access, 128MB, 256MB, and 512MB memory modules organized in a

x72 configuration. These modules use DDR SDRA M devices with four internal banks.

DDR SDRAM modules use a double data rate architecture to achieve high-speed opera-

tion. The double data rate archi t ecture is essentially a 2n-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 DDR SDRAM modules effectively consists of a single

2n-bit-wide, one-clock-cycle data transfer at the internal DRAM core and two corre-

sponding n-bit-wide, one-half-clock-cycle data transfers at the I/O pins.

A bidirectional data strobe (DQS) is transmitted externally, along with data, for use in

data capture at the receiver. DQS is a strobe transmitted by the DDR SDRAM during

READs and by the memory controller during WRITEs. DQS is edge-aligned with data for

READs and center-aligned with data for WRITEs.

DDR SDRAM modules oper ate from differential clock inputs (CK and CK#) ; the crossi ng

of CK going HIGH and CK# going LOW will be referred to as the positive edge of CK.

Control, command, and ad dress signals ar e r egister ed 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

DDR SDRAM modules incorporate serial presence-detect. The SPD function is imple-

mented using a 2,048-bit EEPROM. This nonvolatile storage device contains 256 bytes.

The first 128 bytes are programmed by Micron to identify the module type and various

SDRAM organizations and timing parameters. The remaining 128 bytes of storage are

available for use by the customer. System READ/WRITE operations between the master

(system logic) and the slave EEPROM device (DIMM) occur via a standard I2C bus using

the DIMM’s SCL (clock) and SDA (data) signals, together with SA (2:0), which pro vide

eight unique DIMM/EEPROM addresses. Wr ite protect (WP) is tied to VSS on the

module, permanently disabling hardware write protect.

Electrical Specifications

S tresses greater than those listed in Table8 may cause permanent damage to the

module. This is a stre ss rating only, and functional operation of the module at these or

any other conditions outside thos e ind icated on the device data shee t is not impl ie d .

Exposure to absolute maximum rating conditions for extended periods may adversely

affect reli ability.

Notes: 1. For further information, refer to technical note TN-00-08: “Thermal Applications,” available

on Micron’s Web site.

Input Capacitance

Micron encourages designers to simulate the performance of the module to achieve

optimum values. Simulations are significantly more accurate and realistic than a gross

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.

Component AC Timing and Operating Conditions

Recommended AC operating conditions are gi ven in the DDR component data sheets.

Component specifications are available on Micron’s Web site. Module speed grades

correlate with component speed grades, as shown in Table 9.

Serial Presence-Detect

Notes: 1. To avoid spurious start and stop conditions, a minimum delay is placed 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 resis-

tance, and the EEPROM does not respond to its slave address.
