All rights reserved. 8GB (x64, DR) 288-Pin DDR4 UDIMM Pin Descriptions Pin Descriptions The pin description table below is a comprehensive list of all possible pins for DDR4 modules. All pins listed may not be supported on this module. See Functional Block Diagram for pins specific to this module. Table 5: Pin Descriptions Symbol Type Description Ax Input Address inputs: Provide the row address for ACTIVATE commands and the column address for READ/WRITE commands in order to select one location out of the memory array in the respective bank (A10/AP, A12/BC_n, WE_n/A14, CAS_n/A15, and RAS_n/A16 have additional functions; see individual entries in this table). The address inputs also provide the op-code during the MODE REGISTER SET command. A17 is only defined for x4 SDRAM. A10/AP Input Auto precharge: A10 is sampled during READ and WRITE commands to determine whether an auto precharge should be performed on the accessed bank after a READ or WRITE operation (HIGH = auto precharge; LOW = no auto precharge). A10 is sampled during a PRECHARGE command to determine whether the precharge applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one bank is to be precharged, the bank is selected by the bank group and bank addresses. A12/BC_n Input Burst chop: A12/BC_n is sampled during READ and WRITE commands to determine if burst chop (on-the-fly) will be performed (HIGH = no burst chop; LOW = burst- chopped). See Command Truth Table in the DDR4 component data sheet. ACT_n Input Command input: ACT_n defines the ACTIVATE command being entered along with CS_n. The input into RAS_n/A16, CAS_n/A15, and WE_n/A14 are considered as row address A16, A15, and A14. See Command Truth Table. BAx Input Bank address inputs: Define the bank (with a bank group) to which an ACTIVATE, READ, WRITE, or PRECHARGE command is being applied. Also determine which mode register is to be accessed during a MODE REGISTER SET command. BGx Input Bank group address inputs: Define the bank group to which a REFRESH, ACTIVATE, READ, WRITE, or PRECHARGE command is being applied. Also determine which mode register is to be accessed during a MODE REGISTER SET command. BG[1:0] are used in the x4 and x8 configurations. x16-based SDRAM only has BG0. C0, C1, C2 Input Chip ID: These inputs are used only when devices are stacked; that is, 2H, 4H, and 8H stacks for x4 and x8 configurations using through-silicon vias (TSVs). These pins are not used in the x16 configuration. Some DDR4 modules support a traditional DDP package, which uses CS1_n, CKE1, and ODT1 to control the second die. All other stack configurations, such as a 4H or 8H, are assumed to be single-load (master/slave) type configurations where C0, C1, and C2 are used as chip ID selects in conjunction with a single CS_n, CKE, and ODT. Chip ID is considered part of the command code. CKx_t CKx_c Input Clock: Differential clock inputs. All address, command, and control input signals are sampled on the crossing of the positive edge of CK_t and the negative edge of CK_c. CKEx Input Clock enable: CKE HIGH activates and CKE LOW deactivates the internal clock signals, device input buffers, and output drivers. Taking CKE LOW provides PRECHARGE POWER-DOWN and SELF REFRESH operations (all banks idle), or active power-down (row active in any bank). CKE is asynchronous for self refresh exit. After VREFCA has become stable during the power-on and initialization sequence, it must be maintained during all operations (including SELF REFRESH). CKE must be maintained HIGH throughout read and write accesses. Input buffers (excluding CK_t, CK_c, ODT, RESET_n, and CKE) are disabled during power-down. Input buffers (excluding CKE and RESET#) are disabled during self refresh. CSx_n Input Chip select: All commands are masked when CS_n is registered HIGH. CS_n provides external rank selection on systems with multiple ranks. CS_n is considered part of the command code (CS2_n and CS3_n are not used on UDIMMs).

F 4/16 EN 5 Micron Technology, Inc. reserves the right to change products or specifications without notice. © 2013 Micron Technology, Inc. All rights reserved. 8GB (x64, DR) 288-Pin DDR4 UDIMM Pin Descriptions Table 5: Pin Descriptions (Continued) Symbol Type Description ODTx Input On-die termination: ODT (registered HIGH) enables termination resistance internal to the DDR4 SDRAM. When enabled, ODT (RTT) is applied only to each DQ, DQS_t, DQS_c, DM_n/ DBI_n/TDQS_t, and TDQS_c signal for x4 and x8 configurations (when the TDQS function is enabled via the mode register). For the x16 configuration, RTT is applied to each DQ, DQSU_t, DQSU_c, DQSL_t, DQSL_c, UDM_n, and LDM_n signal. The ODT pin will be ignored if the mode registers are programmed to disable RTT. PARITY Input Parity for command and address: This function can be enabled or disabled via the mode register. When enabled in MR5, the DRAM calculates parity with ACT_n, RAS_n/A16, CAS_n/A15, WE_n/A14, BG[1:0], BA[1:0], A[16:0]. Input parity should be maintained at the rising edge of the clock and at the same time as command and address with CS_n LOW. RAS_n/A16 CAS_n/A15 WE_n/A14 Input Command inputs: RAS_n/A16, CAS_n/A15, and WE_n/A14 (along with CS_n) define the command and/or address being entered and have multiple functions. For example, for activation with ACT_n LOW, these are addresses like A16, A15, and A14, but for a non-activation command with ACT_n HIGH, these are command pins for READ, WRITE, and other commands defined in Command Truth Table. RESET_n CMOS Input SAx Input Serial address inputs: Used to configure the temperature sensor/SPD EEPROM address range on the I2C bus. SCL Input Serial clock for temperature sensor/SPD EEPROM: Used to synchronize communication to and from the temperature sensor/SPD EEPROM on the I2C bus. DQx, CBx I/O Data input/output and check bit input/output: Bidirectional data bus. DQ represents DQ[3:0], DQ[7:0], and DQ[15:0] for the x4, x8, and x16 configurations, respectively. If cyclic redundancy checksum (CRC) is enabled via the mode register, the CRC code is added at the end of the data burst. Any one or all of DQ0, DQ1, DQ2, or DQ3 may be used for monitoring of internal VREF level during test via mode register setting MR[4] A[4] = HIGH; training times change when enabled. DM_n/DBI_n/ TDQS_t (DMU_n, DBIU_n), (DML_n/ DBIl_n) I/O Input data mask and data bus inversion: DM_n is an input mask signal for write data. Input data is masked when DM_n is sampled LOW coincident with that input data during a write access. DM_n is sampled on both edges of DQS. DM is multiplexed with the DBI function by the mode register A10, A11, and A12 settings in MR5. For a x8 device, the function of DM or TDQS is enabled by the mode register A11 setting in MR1. DBI_n is an input/output identifying whether to store/output the true or inverted data. If DBI_n is LOW, the data will be stored/ output after inversion inside the DDR4 device and not inverted if DBI_n is HIGH. TDQS is only supported in x8 SDRAM configurations (TDQS is not valid for UDIMMs). SDA I/O Serial Data: Bidirectional signal used to transfer data in or out of the EEPROM or EEPROM/TS combo device. DQS_t DQS_c DQSU_t DQSU_c DQSL_t DQSL_c I/O Data strobe: Output with read data, input with write data. Edge-aligned with read data, centered-aligned with write data. For x16 configurations, DQSL corresponds to the data on DQ[7:0], and DQSU corresponds to the data on DQ[15:8]. For the x4 and x8 configurations, DQS corresponds to the data on DQ[3:0] and DQ[7:0], respectively. DDR4 SDRAM supports a differential data strobe only and does not support a single-ended data strobe. ALERT_n Output Alert output: Possesses functions such as CRC error flag and command and address parity error flag as output signal. If a CRC error occurs, ALERT_n goes LOW for the period time interval and returns HIGH. If an error occurs during a command address parity check, ALERT_n goes LOW until the on-going DRAM internal recovery transaction is complete. During connectivity test mode, this pin functions as an input. Use of this signal is system-dependent. If not connected as signal, ALERT_n pin must be connected to VDD on DIMMs. EVENT_n Output Temperature event: The EVENT_n pin is asserted by the temperature sensor when critical temperature thresholds have been exceeded. This pin has no function (NF) on modules without temperature sensors. PDF: 09005aef85202c0f atf16c1gx64az.pdf – Rev. F 4/16 EN Active LOW asynchronous reset: Reset is active when RESET_n is LOW and inactive when RESET_n is HIGH. RESET_n must be HIGH during normal operation. 6 Micron Technology, Inc. reserves the right to change products or specifications without notice. © 2013 Micron Technology, Inc. All rights reserved. 8GB (x64, DR) 288-Pin DDR4 UDIMM Pin Descriptions Table 5: Pin Descriptions (Continued) Symbol Type Description TDQS_t TDQS_c Output Termination data strobe: When enabled via the mode register, the DRAM device enables the same RTT termination resistance on TDQS_t and TDQS_c that is applied to DQS_t and DQS_c. When the TDQS function is disabled via the mode register, the DM/TDQS_t pin provides the data mask (DM) function, and the TDQS_c pin is not used. The TDQS function must be disabled in the mode register for both the x4 and x16 configurations. The DM function is supported only in x8 and x16 configurations. DM, DBI, and TDQS are a shared pin and are enabled/disabled by mode register settings. For more information about TDQS, see the DDR4 DRAM component data sheet (TDQS_t and TDQS_c are not valid for UDIMMs). VDD Supply Module power supply: 1.2V (TYP).

All rights reserved. 8GB (x64, DR) 288-Pin DDR4 UDIMM General Description General Description High-speed DDR4 SDRAM modules use DDR4 SDRAM devices with two or four internal memory bank groups. DDR4 SDRAM modules utilizing 4- and 8-bit-wide DDR4 SDRAM devices have four internal bank groups consisting of four memory banks each, providing a total of 16 banks. 16-bit-wide DDR4 SDRAM devices have two internal bank groups consisting of four memory banks each, providing a total of eight banks. DDR4 SDRAM modules benefit from DDR4 SDRAM's use of an 8n-prefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. A single READ or WRITE operation for the DDR4 SDRAM effectively consists of a single 8n-bitwide, four-clock data transfer at the internal DRAM core and eight corresponding n-bitwide, one-half-clock-cycle data transfers at the I/O pins. DDR4 modules use two sets of differential signals: DQS_t and DQS_c to capture data and CK_t and CK_c to capture commands, addresses, and control signals. Differential clocks and data strobes ensure exceptional noise immunity for these signals and provide precise crossing points to capture input signals. Fly-By Topology DDR4 modules use faster clock speeds than earlier DDR technologies, making signal quality more important than ever. For improved signal quality, the clock, control, command, and address buses have been routed in a fly-by topology, where each clock, control, command, and address pin on each DRAM is connected to a single trace and terminated (rather than a tree structure, where the termination is off the module near the connector). Inherent to fly-by topology, the timing skew between the clock and DQS signals can be easily accounted for by using the write-leveling feature of DDR4. Module Manufacturing Location Micron Technology manufactures modules at sites world-wide. Customers may receive modules from any of the following manufacturing locations: Table 8: DRAM Module Manufacturing Locations Manufacturing Site Location Country of Origin Specified on Label Boise, USA USA Aguadilla, Puerto Rico Puerto Rico Xian, China China Singapore Singapore PDF: 09005aef85202c0f atf16c1gx64az.pdf – Rev.

For quad rank modules, ranks 1 and 3 are mirrored and ranks 0 and 2 are non-mirrored. Highlighted address pins have no secondary functions allowing for normal operation when crosswired. Data is still read from the same address it was written. However, Load Mode operations require a specific address. This requires the controller to accommodate for a rank that is "mirrored." Systems may reference DDR4 SPD to determine if the module has mirroring implemented or not. See the JEDEC DDR4 SPD specification for more details.

The SPD data is stored in a 512-byte JEDEC JC-42.4-compliant EEPROM that is segregated into four 128byte, write-protectable blocks. The SPD content is aligned with these blocks as shown in the table below. Block Range Description 0 0–127 1 128–255 080h–0FFh Module-specific parameters 2 256–319 100h–13Fh Reserved; all bytes coded as 00h 320–383 140h–17Fh Manufacturing information 384–511 180h–1FFh End-user programmable 3 000h–07Fh Configuration and DRAM parameters The first 384 bytes are programmed by Micron to comply with JEDEC standard JC-45, "Appendix X: Serial Presence Detect (SPD) for DDR4 SDRAM Modules." The remaining 128 bytes of storage are available for use by the customer. The EEPROM resides on a two-wire I2C serial interface and is not integrated with the memory bus in any way. It operates as a slave device in the I2C bus protocol, with all operations synchronized by the serial clock. Transfer rates of up to 1 MHz are achievable at 2.5V (NOM). Micron implements reversible software write protection on DDR4 SDRAM-based modules. This prevents the lower 384 bytes (bytes 0–383) from being inadvertently programmed or corrupted. The upper 128 bytes remain available for customer use and unprotected. PDF: 09005aef85202c0f atf16c1gx64az.pdf – Rev.

Device functionality is not guaranteed if the DRAM device exceeds the maximum TC during operation. 4. If TC exceeds 85°C, the DRAM must be refreshed externally at 2X refresh, which is a 3.9µs interval refresh rate. 5. The refresh rate must double when 85°C < TOPER ≤ 95°C. 6. Storage temperature is defined as the temperature of the top/center of the DRAM and does not reflect the storage temperatures of shipping trays. 7.

Component specifications are available at micron.com. Module speed grades correlate with component speed grades, as shown below. Table 13: Module and Component Speed Grades DDR4 components may exceed the listed module speed grades; module may not be available in all listed speed grades Module Speed Grade Component Speed Grade -2G6 -075 -2G4 -083E -2G3 -083 -2G1 -093E -1G9 -107E Design Considerations Simulations Micron memory modules are designed to optimize signal integrity through carefully designed terminations, controlled board impedances, routing topologies, trace length matching, and decoupling. However, good signal integrity starts at the system level. Micron encourages designers to simulate the signal characteristics of the system's memory bus to ensure adequate signal integrity of the entire memory system. Power Operating voltages are specified at the edge connector of the module, not at the DRAM. Designers must account for any system voltage drops at anticipated power levels to ensure the required supply voltage is maintained. PDF: 09005aef85202c0f atf16c1gx64az.pdf – Rev.
