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.
Description
IDT DDR4 RCD register and DB data buffer enable RDIMM and LRDIMM to faster speeds and deeper memories. This video helps you understand the DDR4 feature enhancements of IDT's DDR4 RCD and DB compared to earlier DDR3 technology. An introduction to some available LeCroy testing and debug tools complete the video. Presented by Douglas Malech, Product Marketing Manager at IDT, and Mike Micheletti, Product Manager at Teledyne LeCroy.
