Rev. 1.22, 2007-08 03292006-6N25-8R3I 3 Internet Data Sheet HYS72D[64/128/256]xxxHBR–[5/6]–C Registered Double-Data-Rate SDRAM Module 1.2 Description The HYS72D[64/128/256]xxxHBR–[5/6]–C are low-profile versions of the standard Registered DIMM modules with 1.1inch (28.58 mm) and 1.2-inch (30.40 mm) height for Server Applications. The low-profile DIMM versions are available as 64M ×72 (512MB), 128M ×72 (1 GB), and 256M ×72 (2 GB). The memory array is designed with Double-Data-Rate Synchronous DRAMs for ECC applications. All control and address signals are re-driven on the DIMM using register devices and a PLL for the clock distribution. This reduces capacitive loading to the system bus, but adds one cycle to the SDRAM timing. A variety of decoupling capacitors are mounted on the PC board. The DIMMs feature serial presence detect based on a serial E2PROM device using the 2-pin I2C protocol. The first 128 bytes contain factory programmed configuration data and the second 128 bytes are made available to the customer.

Peak to peak AC noise on VREF may not exceed ± 2% VREF.DC. VREF is also expected to track noise variations in VDDQ. VTT is not applied directly to the device. 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. Inputs are not recognized as valid until VREF stabilizes. VID is the magnitude of the difference between the input level on CK and the input level on CK. The ratio of the pull-up current to the pull-down current is specified for the same temperature and voltage, over the entire temperature and voltage range, for device drain to source voltage from 0.25 to 1.0 V. For a given output, it represents the maximum difference between pull-up and pull-down drivers due to process variation. Values are shown per pin.

CK/CK slew rate are ≥ 1.0 V/ns. 4) Inputs are not recognized as valid until VREF stabilizes. 5) The Output timing reference level, as measured at the timing reference point indicated in AC Characteristics (note 3) is VTT. 6) For each of the terms, if not already an integer, round to the next highest integer. tCK is equal to the actual system clock cycle time.

These parameters are not referred to a specific voltage level, but specify when the device is no longer driving (HZ), or begins driving (LZ). 8) Fast slew rate ≥ 1.0 V/ns , slow slew rate ≥ 0.5 V/ns and < 1 V/ns for command/address and CK & CK slew rate > 1.0 V/ns, measured between VIH(ac) and VIL(ac). 9) These parameters guarantee device timing, but they are not necessarily tested on each device. 10) A maximun of eight Autorefresh commands can be posted to any given DDR SDRAM device 11) 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 specificationsof 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 at this time, depending on tDQSS. 12) 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.

One feature is externally controlled via a system-generated RESET signal; the second is based on module detection of the input clocks. These enhancements permit the modules to power up with SDRAM outputs in a High-Z state (eliminating risk of high current dissipations and/or dotted I/Os), and result in the powering-down of module support devices (registers and Phase-Locked Loop) when the memory is in Self-Refresh mode. The new RESET pin controls power dissipation on the module’s registers and ensures that CKE and other SDRAM inputs are maintained at a valid ‘low’ level during power-up and self refresh. When RESET is at a low level, all the register outputs are forced to a low level, and all differential register input receivers are powered down, resulting in very low register power consumption. The RESET pin, located on DIMM tab #10, is driven from the system as an asynchronous signal according to the attached details. Using this function also permits the system and DIMM clocks to be stopped during memory Self Refresh operation, while ensuring that the SDRAMs stay in Self Refresh mode. TABLE 16 Function for RESET Register Outputs1) Register Inputs RESET CK CK Data in (D) Data out (Q) H Rising Falling H H H Rising Falling L L H L or H L or H X Qo H High Z High Z X Illegal input conditions L X or Hi-Z X or Hi-Z X or Hi-Z L 1) X : Don’t care, Hi-Z : High Impedance, Qo: Data latched at the previous of CK risning and CK falling As described in the table above, a low on the RESET input ensures that the Clock Enable (CKE) signal(s) are maintained low at the SDRAM pins (CKE being one of the 'Q' signals at the register output). Holding CKE low maintains a high impedance state on the SDRAM DQ, DQS and DM outputs — where they will remain until activated by a valid ‘read’ cycle. CKE low also maintains SDRAMs in Self Refresh mode when applicable. The DDR PLL devices automatically detect clock activity above 20MHz. When an input clock frequency of 20MHz or greater is detected, the PLL begins operation and initiates clock frequency lock (the minimum operating frequency at which all specifications will be met is 95MHz). If the clock input frequency drops below 20MHz (actual detect frequency will vary by vendor), the PLL VCO (Voltage Controlled Oscillator) is stopped, outputs are made High-Z, and the differential inputs are powered down — resulting in a total PLL current consumption of less than 1mA. Use of this low power PLL function makes the use of the PLL RESET (or G pin) unnecessary, and it is tied inactive on the DIMM. This application note describes the required and optional system sequences associated with the DDR Registered DIMM 'RESET' function. It is important to note that all references to CKE refer to both CKE0 and CKE1 for a 2-bank DIMM. Because RESET applies to all DIMM register devices, it is therefore not possible to uniquely control CKE to one physical DIMM bank through the use of the RESET pin.

The system sets RESET at a valid low level. This is the preferred default state during power-up. This input condition forces all register outputs to a low state independent of the condition on the register inputs (data and clock), ensuring that CKE is at a stable low-level at the DDR SDRAMs. 2. The power supplies should be initialized according to the JEDEC-approved initialization sequence for DDR SDRAMs. 3. Stabilization of Clocks to the SDRAM The system must drive clocks to the application frequency (PLL operation is not assured until the input clock reaches 20MHz). Stability of clocks at the SDRAMs will be affected by all applicable system clock devices, and time must be allotted to permit all clock devices to settle. Once a stable clock is received at the DIMM PLL, the required PLL stabilization time (assuming power to the DIMM is stable) is 100 microseconds. When a stable clock is present at the SDRAM input (driven from the PLL), the DDR SDRAM requires 200 µsec prior to SDRAM operation. 4. The system applies valid logic levels to the data inputs of the register (address and controls at the DIMM connector). CKE must be maintained low and all other inputs should be driven to a known state. In general these commands can be determined by the system designer. One option is to apply an SDRAM ‘NOP’ command (with CKE low), as this is the first command defined by the JEDEC initialization sequence (ideally this would be a ‘NOP Deselect’ command). A second option is to apply low levels on all of the register inputs to be consistent with the state of the register outputs. 5. The system switches RESET to a logic ‘high’ level. The SDRAM is now functional and prepared to receive commands. Since the RESET signal is asynchronous, setting the RESET timing in relation to a specific clock edge is not required (during this period, register inputs must remain stable). 6. The system must maintain stable register inputs until normal register operation is attained. The registers have an activation time that allows their clock receivers, data input receivers, and output drivers sufficient time to be turned on and become stable. During this time the system must maintain the valid logic levels described in step 5. It is also a functional requirement that the registers maintain a low state at the CKE outputs to guarantee that the DDR SDRAMs continue to receive a low level on CKE. Register activation time (t (ACT) ), from asynchronous switching of RESET from low to high until the registers are stable and ready to accept an input signal, is specified in the register and DIMM do-umentation. 7. The system can begin the JEDEC-defined DDR SDRAM power-up sequence (according to the JEDEC-pproved initialization sequence). Self Refresh Entry (RESET low, clocks powered off) — Optional Self Refresh can be used to retain data in DDR SDRAM DIMMs even if the rest of the system is powered down and the clocks are off. This mode allows the DDR SDRAMs on the DIMM to retain data without external clocking. Self Refresh mode is an ideal time to utilize the RESET pin, as this can reduce register power consumption (RESET low deactivates register CK and CK, data input receivers, and data output drivers). • The system applies Self Refresh entry command. (CKE→Low, CS→Low, RAS → Low, CAS→ Low, WE→ High) Note: The commands reach the DDR SDRAM one clock later due to the additional register pipelining on a Registered DIMM. After this command is issued to the SDRAM, all of the address and control and clock input conditions to the SDRAM are Don’t Cares— with the exception of CKE. • The system sets RESET at a valid low level. This input condition forces all register outputs to a low state, independent of the condition on the registerm inputs (data and clock), and ensures that CKE, and all other control and address signals, are a stable low-level at the DDR SDRAMs. Since the RESET signal is asynchronous, setting the RESET timing in relation to a specific clock edge is not required. • The system turns off clock inputs to the DIMM. (Optional) a. In order to reduce DIMM PLL current, the clock inputs to the DIMM are turned off, resulting in High-Z clock inputs to both the SDRAMs and the registers. This must be done after the RESET deactivate time of the register (t (INACT) ). The deactivate time defines the time in which the clocks and the control and address signals must maintain valid levels after RESET low has been applied and is specified in the register and DIMM documentation. b. The system may release DIMM address and control inputs to High-Z. This can be done after the RESET deactivate time of the register. The deactivate time defines the time in which the clocks and the control and the address signals must maintain valid levels after RESET low has been applied. It is highly recommended that CKE continue to remain low during this operation.

Self Refresh Exit (RESET low, clocks powered off) — Optional 1. Stabilization of Clocks to the SDRAM. The system must drive clocks to the application frequency (PLL operation is not assured until the input clock reaches ~20MHz). Stability of clocks at the SDRAMs will be affected by all applicable system clock devices, and time must be allotted to permit all clock devices to settle. Once a stable clock is received at the DIMM PLL, the required PLL stabilization time (assuming power to the DIMM is stable) is 100 microseconds. 2. The system applies valid logic levels to the data inputs of the register (address and controls at the DIMM connector). CKE must be maintained low and all other inputs should be driven to a known state. In general these commands can be determined by the system designer.

The SDRAM is now functional and prepared to receive commands. Since the RESET signal is asynchronous, RESET timing relationship to a specific clock edge is not required (during this period, register inputs must remain stable). 4. The system must maintain stable register inputs until normal register operation is attained. The registers have an activation time that allows the clock receivers, input receivers, and output drivers sufficient time to be turned on and become stable. During this time the system must maintain the valid logic levels described in Step 2. It is also a functional requirement that the registers maintain a low state at the CKE outputs to guarantee that the DDR SDRAMs continue to receive a low level on CKE. Register activation time (t (ACT) ), from asynchronous switching of RESET from low to high until the registers are stable and ready to accept an input signal, is specified in the register and DIMM do-umentation. 5. System can begin the JEDEC-defined DDR SDRAM Self Refresh Exit Procedure. Self Refresh Entry (RESET low, clocks running) — Optional Although keeping the clocks running increases power consumption from the on-DIMM PLL during self refresh, this is an alternate operating mode for these DIMMs. 1. System enters Self Refresh entry command. (CKE→ Low, CS→ Low, RAS→ Low, CAS→ Low, WE→ High) Note: The commands reach the DDR SDRAM one clock later due to the additional register pipelining on a Registered DIMM. After this command is issued to the SDRAM, all of the address and control and clock input conditions to the SDRAM are Don’t Cares — with the exception of CKE. • The system sets RESET at a valid low level. This input condition forces all register outputs to a low state, independent of the condition on the data and clock register inputs, and ensures that CKE is a stable low-level at the DDR SDRAMs. • The system may release DIMM address and control inputs to High-Z. This can be done after the RESET deactivate time of the register (t (INACT) ). The deactivate time describes the time in which the clocks and the control and the address signals must maintain valid levels after RESET low has been applied. It is highly recommended that CKE continue to remain low during the operation. • The DIMM is in a low power, Self Refresh mode. Self Refresh Exit (RESET low, clocks running) — Optional 1.

The SDRAM is now functional and prepared to receive commands. Since the RESET signal is asynchronous, it does not need to be tied to a particular clock edge (during this period, register inputs must continue to remain stable). 3. The system must maintain stable register inputs until normal register operation is attained. The registers have an activation time that allows the clock receivers, input receivers, and output drivers sufficient time to be turned on and become stable. During this time the system must maintain the valid logic levels described in Step 1. It is also a functional requirement that the registers maintain a low state at the CKE outputs in order to guarantee that the DDR SDRAMs continue to receive a low level on CKE. This activation time, from asynchronous switching of RESET from low to high, until the registers are stable and ready to accept an input signal, is t (ACT ) as specified in the register and DIMM documentation. 4. The system can begin JEDEC defined DDR SDRAM Self Refresh Exit Procedure. Self Refresh Entry/Exit (RESET high, clocks running) — Optional As this sequence does not involve the use of the RESET function, the JEDEC standard SDRAM specification explains in detail the method for entering and exiting Self Refresh for this case. Self Refresh Entry (RESET high, clocks powered off) — Not Permissible In order to maintain a valid low level on the register output, it is required that either the clocks be running and the system drive a low level on CKE, or the clocks are powered off and RESET is asserted low according to the sequence defined in this application note. In the case where RESET remains high and the clocks are powered off, the PLL drives a High-Z clock input into the register clock input. Without the low level on RESET an unknown DIMM state will result.
