LRDIMM (load-reduced dual inline memory module) is a load-reduction (LR) DIMM (used in servers) that enables higher densities than RDIMMs and includes a memory buffer (MB) chip instead of a register to decrease and limit the load on the server memory bus.
The memory buffer consolidates each clock, command, address, and data input into a single load, resulting in faster memory access.
In data centres, cloud computing, and high-performance computing (HPC) environments, LRDIMMs are beneficial in memory-intensive applications.
They are more expensive than RDIMM chips, but they offer superior performance for memory-intensive applications.
The Global Load Reduced DIMM (LRDIMM) Market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2022 to 2027.
Cadence introduces the JEDEC DDR4 LRDIMM memory device as a gold standard for IP, SoC, and system-level design verification.
The JEDEC DDR4 Unbuffered DIMM (UDIMM), Registered DIMM (RDIMM), and Load-Reduced DIMM (LRDIMM) design specifications are supported by this Cadence Verification IP (VIP).
It offers a mature, competent compliance verification solution that includes simulation and formal analysis, making it suitable for IP, SoC, and system-level verification.
The DDR4 DIMM standard is the next generation of DIMMs, including improvements in performance, configuration, reliability, and power consumption.
It can handle speeds of up to 3200 rpm. It is more versatile because of a redesigned Control Word Write, DRAM Mode register write interface, and additional control word settings including programmable latency and encoded quad modes.
This is more reliable since the command delivered to DRAMs and the RCD Control word writes are protected with optional parity checking and thorough specification for multiple techniques of recovering from parity mistakes.
