Description

The 4DB0232KD is a JEDEC compliant DDR4 Data Buffer with dual 4-bit bidirectional “DQ” data registers and “DQS” differential strobes. It is designed for 1.2 VDD operation in DDR4 LRDIMM applications. The DQ host interface side of each 4-bit bidirectional data register is connected to a memory controller while the MDQ interface side is connected to two x4 DRAMs. The 4DB0232KD supports speeds up to 3200 just like the 4DB0232KC, but also has improved power efficiency.

    With the introduction of 8Gb DRAMs, Load-Reduced DIMMs (LRDIMMs) now outperform Registered DIMMs (RDIMMs) by offering both higher memory capacity and bandwidth. This paper demonstrates how 32GB 2Rx4 LRDIMMs based on 8Gb DDR4 DRAMs provide a superior solution for enterprise servers requiring deep memory and fast data access.

A white paper authored by IDT (acquired by Renesas) and Micron details research into memory and bandwidth for today's high-performance servers. LRDIMMS and RDIMMS traditionally have been seen as complementary, with the former targeting applications requiring deeper memory and the latter for applications requiring higher bandwidth. 

The introduction of 8-gigabit DRAMS has resulted in a growing number of Internet applications benefiting from both deeper memories and higher bandwidth. This paper shows how 32 GB 2RX4 LRDIMMs transcend similar RDIMMs to meet the needs of today’s data center enterprise servers, by providing an optimal combination of deeper memory and higher data bandwidth, even at mainstream module densities.
