DDR5 Multiplexed Registering Clock Driver (MRCD) and Multiplexed Data Buffer (MDB)
Delivering industry-leading memory bandwidth and capacity
The Rambus DDR5 Multiplexed Registering Clock Driver (MRCD) and Multiplexed Data Buffer (MDB) enable industry-standard DDR5 Multiplexed Rank DIMMs (MRDIMMs) operating at data rates up to 12,800 MT/s.
| Description | Part Number | Applications |
|---|---|---|
| 12800 MT/s Multiplexed Registering Clock Driver | D5MRCD2GXX | Server MRDIMM 12800 |
| 12800 MT/s Multiplexed Data Buffer | D5MDB2XGXX | Server MRDIMM 12800 |
Each DDR5 MRDIMM 12800 requires one MRCD and ten MDB chips to multiplex the memory channel. The MRCD and MDB will also support a Tall MRDIMM form factor with four ranks of DDR5 DRAMs for double the capacity of a dual-rank RDIMM in a cost-effective manner.
Data Center Evolution: DDR5 DIMMs Advance Server Performance
Driven by a confluence of megatrends, global data traffic is increasing at an exponential rate. For example, 5G networks are enabling billions of AI-powered IoT devices untethered from wired networks. Nowhere is the impact of all this growth being felt more intensely than in data centers. Indeed, hyperscale data centers have become the critical hubs of the global data network. DDR5 DRAM will enable the next generation of server systems providing the massive computing power of hyperscale and enterprise data centers. Learn about the benefits of DDR5 memory and the design considerations for implementing DDR5 DIMMs.
