240pin Fully Buffered DDR2 SDRAM DIMMs based on 512 Mb F-ver. This Hynix's Fully Buffered DIMM is a high-bandwidth & large capacity channel solution that has a narrow host interface. Hynix's FB-DIMM features novel architecture including the Advanced Memory Buffer that isolates the DDR2 SDRAMs from the channel. This single component located in the front side center of each DIMM, acts as a repeater and buffer for all signals and commands which are exchanged between the host controller and the DDR2 SDRAMs including data in and output. The AMB communicates with the host controller and adjacent DIMMs on a system board using an industry standard Differential Point to Point Link Interface at 1.5V power. The AMB also allows buffering of memory traffic to support large memory capacities. All memory control for the DDR2 SDRAM devices resides in the host, including memory request initiation, timing, refresh, scrubbing, sparing, configuration access and power management. The AMB interface is responsible for handling channel and memory requests to and from the local FBDIMM and for forwarding request to other FBDIMMs on the memory channel.

Advanced Memory Buffer Overview The Advanced Memory Buffer reference design complies with the JEDEC FB-DIMM Architecture and Protocol Specification. 2. Advanced Memory Buffer Functionality 2.1 Advanced Memory Buffer * * * * * * * * * * Supports channel initialization procedures as defined in the initialization chapter of the FB-DIMM Architecture and Protocol Specification to align the clocks and the frame boundaries verify channel connectivity and identify AMB DIMM position. Supports the forwarding of southbound and northbound frames, servicing requests directed to DIMM, as defined in the protocol chapter, and merging the return data into the northbound frames. If the AMB resides on the last DIMM in the channel, the AMB initializes northbound frames. Detects errors on the channel and reports them to the host memory controller. Acts as DRAM memory buffer for all read, write and configuration accesses addressed to the DIMM. Provides a read buffer FIFO and a write buffer FIFO. Supports an SMBus protocol interface for access to the AMB configuration registers. Provides logic to support MEMBIST and IBIST Design for Test functions. Provides a register interface for the thermal sensor and status indicator. Functions as a repeater to extend the maximum length of FBD Links. 2.2 Transparent Mode for DRAM Test Support In this mode, the Advanced Memory Buffer will provide lower speed tester access to DRAM pins through the FB-DIMM I/O pins. This allows the tester to send and arbitrary test pattern to the DRAMs. Transparent mode only supports a maximum DRAM frequency equivalent to DDR2 400. Transparent mode functionality: * * * Reconfigure FB-DIMM inputs from differential high speed link receivers to two single ended lower speed receivers(~200 Mhz) These inputs directly control DDR2 Command/Address and input data that is replicated to all DRAMs Used low speed direct drive FB-DIMM outputs to bypass high speed Parallel/Serial circuitry and provide test results back to tester 2.3 DDR2 SDRAM * * * Supports DDR2 at speeds of 533,667 and 800 MT/s Supports 512Mb devices in x4 and x8 configurations 72 bit DDR2 SDRAM memory array Rev 1.0 / July 2008 13 1240pin Fully Buffered DDR2 SDRAM DIMMs 3.

Interfaces Below Figure illustrates the AMB and all of its interfaces.They consists of two FB-DIMM links, one DDR2 channel and an SMBus interface. Each FB-DIMM link connects the AMB to a host memory controller or an adjacent FB-DIMM. The DDR2 channel supports direct connection to the DDR2 SDRAMs on a Fully Buffered DIMM.

The southbound input link is 10 lanes wid and carries commands and write data from the host memory controller or the adjacent DIMM in the host direction. The southbound output link forwards this same data to the next FBD. The northbound input link is 13 to 14 lanes wide and carries read return data or status information from the next FB-DIMM in the chain back towards the host. The northbound output link forwards this information back towards the host and multiplexes in any read return data or status information that is generated internally. 4.2 DDR2 Channel The DDR2 channel on the Advanced Memory Buffer supports direct connection to DDR2 SDRAMs. The DDR2 channel supports two ranks of eight banks with 16 row/column request, 64 data signals, and eight check-bit signals. There are two copies of address and command signals to support DIMM routing and electrical requirements. Four transfer bursts are driven on the data and check-bit lines at 800 MHz. Propagation delays between read data/check-bit strobe lanes on a given channel can differ. Each strobe can be calibrated by hardware state machines using write/read trial and error. Hardware aligns the read data and check-bits to a single core clock. The Advanced Memory Buffer provides four copies of the command clock phase references(CLK[3:0]) and write data/check-bit strobes(DQSs) for each DRAM nibble. Rev 1.0 / July 2008 15 1240pin Fully Buffered DDR2 SDRAM DIMMs 4.3 SMBus Slave Interface The Advanced Memory Buffer supports an SMBus interface to allow system access to configuration registers independent of the FB-DIMM link. The Advanced Memory Buffer will never be a master on the SMBus, only a slave. Serial SMBus data transfer is supported at 100 kHz. SMBus access to the Advanced Memory Buffer may be a requirement to boot and to set link strength, frequency and other parameters needed to insure robust configurations. It is also required for diagnostic support when the link is down. The SMBus address straps located on the DIMM connector are used by the unique ID. 4.4 FBD Channel Latency FB-DIMM channel latency is measured from the time a read request is driven on the FB-DIMM channel pins to the time when the first 16 bytes (2nd chunk) of read completion data is sampled by the memory controller. When not using the Variable Read Latency capability, the latency for a specific DIMM on a channel is always equal to the latency for any other DIMM on that channel. However, the latency for each DIMM in a specific configuration with some number of DIMMs installed. As more DIMMs are added to the channel, additional latency is required to read from each DIMM on the channel. Because the channel is based on the point to point interconnection of buffer components between DIMMs, memory requests are required to travel through N-1 buffers before reaching the Nth buffer. The result is that a 4 DIMM channel configuration will have greater idle read latency compared to a 1DIMM channel configuration.The Variable Read Latency capability can be used to reduce latency for DIMMs closer to the host. The idle latencies listed in this section are representative of what might be achieved in typical AMB designs. Actual implementations with latencies less than the values listed will have higher application performance and vice versa. 4.5 Peak Theoretical Throughput An FB-DIMM channel transfers read completion data on the FBD Northbound data connection. 144 bits of data are transferred for every FBD Northbound data frame. This matches the 18-byte data transfer of an ECC DDR DRAM in a single DRAM command clock. A DRAM burst of 8 from a single channel or a DRAM burst of four from two lock stepped channels provides a total of 72 bytes of data(64 bytes plus 8 bytes ECC) The FBD frame rate matches the DRAM command clock because of the fixed 6:1 ratio of the FBD channel clock to the DRAM command clock. Therefore, the Northbound data connection will exhibit the same peak theoretical throughput as a single DRAM channel. For example, when using DDR2 533 DRAMs, the peak theoretical throughput as a single DRAM channel.For example, when using DDR2 533 DRAMs, the peak theoretical bandwidth of the Northbound data connection is 4.276 GB/sec. Write data is transferred on the FBD Southbound command and data connection, via Command+Wdata frames. 72 bits of data are transferred for every FBD Command+Wdata frame. Two Command+Wdata frames match the 18-byte data transfer of and ECC DDR DRAM in a single DRAM command clock. A DRAM burst of 8 transfers from a single channel, or a burst of 4 from two lock-step channels provides a total of 72 bytes of data(64 bytes plus & bytes ECC) When the FBD frame rate matches the DRAM command clock, the Southbound command and data connection will exhibit one half the peak theoretical throughput of a single DRAM channel. For example, when using DDR2 533 DRAMs, the peak theoretical bandwidth of the Southbound command and data connection is 2.133 GB/sec. The total peak theoretical throughput for a single FBD channel is defined as the sum of the peak theoretical throughput of the Northbound data connection and the Southbound command and data connection. When the FBD frame rate matches the DRAM command clock, this is equal to 1.5 times the peak theoretical throughput of a single DRAM channel. For example, when using DDR2 533 DRAMs, the peak theoretical throughput of a DDR2 533 channel would be 4.267 GB/sec, while the peak theoretical throughput of and FBD -/+533 channel would be 6.4 GB/sec. Rev 1.0 / July 2008 16 1240pin Fully Buffered DDR2 SDRAM DIMMs 5 Hot-add The FB-DIMM channel does not provide a mechanism to automatically detect and report the addition of a new DIMM south of the currently active last DIMM. It is assumed the system will be notified through some means of the addition of one or more new DIMMs so that specific commands can be sent to the host controller to initialize the newly added DIMM(s) and perform a Hot-add Reset to bring them into the channel timing domain. It should be noted that the power to the DIMM socket must be removed before a "hot-add" DIMM is inserted or removed. Applying or removing the power to a DIMM socket is a system platform function. 6 Hot-remove In order to accomplish removal of DIMMs the host must perform a Fast Reset sequence targeted at the last DIMM that will be retained on the channel. The Fast Reset re-establish the appropriate last DIMM so that the Southbound Tx outputs of the last DIMM and the Southbound and Northbound outputs of the DIMMs beyond the last active DIMM are disabled. Once the appropriate outputs are disabled the system can coordinate the procedure to remove power in preparation for physical removal of the DIMM if needed. It should be noted that the power to the DIMM socket must be removed before a "hot-add" DIMM is inserted or removed. Applying or removing the power to a DIMM socket is a system platform function. 7 Hot-replace Hot replace of DIMM is accomplished through combing th Hot-Remove and Hot-Add process.
