Input/Output Functional Description

Symbol Type Polarity Function

CK0, CK1, CK2,

CK0, CK1, CK2 (SSTL) Cross

point

The system clock inputs. All address and command lines are sampled on the cross point of

the rising edge of CK and falling edge of CK. A Delay Locked Loop (DLL) circuit is driven

from the clock inputs and output timing for read operations is synchronized to the input

clock.

CKE0, CKE1 (SSTL) Active

High

Activates the DDR SDRAM CK signal when high and deactivates the CK signal when lo w.

By

deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh

mode.

S0, S1 (SSTL) Active

Low

Enables the associated DDR SDRAM command decoder when low and disables the

command

decoder when high. When the command decoder is disabled, new commands are

ignored but previous operations continue. Physical Bank 0 is selected by S

0; Bank 1 is

selected by S1.

RAS, CAS, WE (SSTL) Active

Low When sampled at the positive rising edge of the clock, RAS, CAS, WE

define the operation to

be executed by the SDRAM.

VREF Supply

Reference voltage for SSTL-2 inputs

VDDQ Supply Isolated pow

er supply for the DDR SDRAM output buffers to provide improved noise

immunity

BA0, BA1 (SSTL) -

Selects which SDRAM bank is to be active.

A0 - A9

A10/AP

A1 1, A12 (SSTL) -

During a Bank Activate command cycle, A0-A12 defines the row address (RA0-RA12) whe

n

sampled at the rising clock edge.

During a Read or Write command cycle, A0-A9 defines the column address (CA0-CA9

)

when sampled at the rising clock edge. In addition to the column address, AP is used to

invoke auto-precharge operation at the end of the B

urst Read or Write cycle. If AP is high,

auto-

precharge is selected and BA0/BA1 defines the bank to be precharged. If AP is low,

auto-precharge is disabled.

During a Precharge command cycle, AP is used in conjunction with BA0/BA1 to control

which bank(s) t

o precharge. If AP is high all 4 banks will be precharged regardless of the

state of BA0/BA1. If AP is low, then BA0/BA1 are used to define which bank to pre-charge.

DQ0 - DQ63 (SSTL) -

Data and Check Bit input/output pins operate in the same manner as on

conventional

DRAMs.

DQS0 - DQS7,

DQS9 – DQS16 (SSTL) Active

High

Data strobes: Output with read data, input with write data. Edge aligned with read data,

centered on write data. Used to capture write data.

CB0 – CB7 (SSTL) - Data Check Bit Input/Output pins. Used on ECC modules and is not used on x64 modules.

DM0 – DM8 Input Active

High

The data write masks, associated with one data byte. In Write mode, DM operates as a byte

mask by allowing input data to be written if it is low but blocks the write op

eration if it is high.

In Read mode, DM lines have no effect. DM8 is associated with check bits CB0-

CB7, and is

not used on x64 modules.

VDD, VSS Supply

Power and ground for the DDR SDRAM input buffers and core logic

SA0 – SA2 -

Address inputs. Connected to either VDD or VSS

on the system board to configure th e Serial

Presence Detect EEPROM address.

SDA -

This bi-

directional pin is used to transfer data into or out of the SPD EEPROM. A resistor

must be connected from the SDA bus line to V DD to act as a pull-up.

SCL -

This signal is used to clock data into and out of the SPD EEPROM. A resistor may be

connected from the SCL bus time to V DD to act as a pull-up.

VDDSPD Supply

Serial EEPROM positive power supply.

1. Inputs are not recognized as valid until VREF stabilizes.

2. VREF is expected to be equal to 0.5 VDDQ of the transmitting device, and to track variations in the DC level of the same. Peak-to-peak

noise on VREF may not exceed 2% of the DC value.

3. VTT is not applied directly to the DIMM. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF,

and must track variations in the DC level of VREF.

4. VID is the magnitude of the difference between the input level on CK and the input level on CK.

AC Characteristics

Notes 1-5 apply to the following Tables; Electrical Characteristics and DC Operating Conditions, AC Operating

Conditions, Operating, Standby, and Refresh Currents, and Electrical Characteristics and AC Timing.)

1. All voltages referenced to VSS.

2. Tests for AC timing, IDD, and electrical, AC and DC characteristics, may be conducted at nominal reference/supply voltage levels, but the

related specifications and device operation are guaranteed for the full voltage range specified.

3. Outputs measured with equivalent load. Refer to the AC Output Load Circuit below.

4. AC timing and IDD tests may use a VIL to VIH swing of up to 1.5V in the test environment, but input timing is still referenced to VREF (or to

the crossing point for CK, CK), and parameter specifications are guaranteed for the specified AC input levels under normal use conditions.

The minimum slew rate for the input signals is 1V/ns in the range between VIL (AC) and VIH (AC) unless otherwise specified.

5. The AC and DC input level specifications are as defined in the SSTL_2 Standard (i.e. the receiver effectively switches as a result of the

signal crossing the AC input level, and remains in that state as long as the signal does not ring back above (below) the DC input LOW

(HIGH) level.

AC Timing Specification Notes

1. Input slew rate = 1V/ns.

2. The CK/CK input reference level (for timing reference to CK/CK) is the point at which CK and CK cross: the input reference level for

signals other than CK/CK is VREF.

3. Inputs are not recognized as valid until VREF stabilizes.

4. The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (Note 3) is VTT.

5. tHZ and tLZ transitions occur in the same access time windows as valid data transitions. These parameters are not referred to a specific

voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ).

6. The maximum limit for this parameter is not a device limit. The device operates with a greater value for this parameter, but system

performance (bus turnaround) degrades accordingly.

7. The specific requirement is that DQS be valid (high, low, or some point on a valid transition) on or before this CK edge. A valid transition

is defined as monotonic and meeting the input slew rate specifications of the device. When no writes were previously in progress on the

bus, DQS will be transitioning from Hi-Z to logic LOW. If a previous write was in progress, DQS could be HIGH, LOW, or transitioning from

high to low at this time, depending on tDQSS.

8. A maximum of eight Auto refresh commands can be posted to any given DDR SDRAM device.

9. For command/address input slew rate >= 1.0 V/ns. Slew rate is measured between VOH (AC) and VOL (AC).

10. For command/address input slew rate >= 0.5 V/ns and < 1.0 V/ns. Slew rate is measured between VOH (AC) and VOL (AC).

11. CK/CK slew rates are >= 1.0 V/ns.

12. These parameters guarantee device timing, but they are not necessarily tested on each device, and they may be guaranteed by design

or tester characterization.

13. For each of the terms in parentheses, if not already an integer, round to the next highest integer. tCK is equal to the actual system clock

cycle time. For example, for PC2100 at CL= 2.5, tDAL = (15ns/7.5ns) +(20ns/7.0ns) = 2 + 3 = 5.

14. An input setup and hold time derating table is used to increase tIS and tIH in the case where the input slew rate is below 0.5 V/ns.

Input Slew Rate Delta (tIS) Delta (tIH) Unit Note

0.5 V/ns 0 0 ps 1, 2

0.4 V/ns +50 0 ps 1, 2

0.3 V/ns +100 0 ps 1, 2

1. Input slew rate is based on the lesser of the slew rates determined by either VIH (AC) to VIL (AC) or VIH (DC) to VIL (DC), similarly for rising

transitions.

2. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.

15. An input setup and hold time derating table is used to increase tDS and tDH in the case where the I/O slew rate is below 0.5 V/ns.

Input Slew Rate Delta (tDS) Delta (tDH) Unit Note

0.5 V/ns 0 0 ps 1, 2

0.4 V/ns +75 +75 ps 1, 2

0.3 V/ns +150 +150 ps 1, 2

1. I/O slew rate is based on the lesser of the slew rates determined by either VIH (AC) to VIL (AC) or VIH (DC) to VIL (DC), similarly for rising

transitions.

2. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.

16. An I/O Delta Rise, Fall Derating table is used to increase tDS and tDH in the case where DQ, DM, and DQS slew rates differ.

Delta Rise and Fall Rate Delta (tDS) Delta (tDH) Unit Note

0.0 ns/V 0 0 ps 1-4

0.25 ns/V +50 +50 ps 1-4

0.5 ns/V +100 +100 ps 1-4

1. Input slew rate is based on the lesser of the slew rates determined by either VIH (AC) to VIL (AC) or VIH (DC) to VIL (DC), similarly for rising

transitions.

2. Input slew rate is based on the larger of AC to AC delta rise, fall rate and DC to DC delta rise, fall rate.

3. The delta rise, fall rate is calculated as: [1/(slew rate 1)] - [1/(slew rate 2)]

For example: slew rate 1 = 0.5 V/ns; slew rate 2 = 0.4 V/ns. Delta rise, fall = (1/0.5) - (1/0.4) [ns/V] = -0.5 ns/V

Using the table above, this would result in an increase in tDS and tDH of 100 ps.

4. These derating parameters may be guaranteed by design or tester characterization and are not necessarily tested on each device.
