Apacer XR-LRDIMM anti-vibration server memory module
To aid the design of defence projects, Apacer has successfully developed an anti-vibration server memory for defence applications. It’s called XR-LRDIMM (Extreme Rugged Load-Reduced DIMM), and it features strengthened shock and vibration resistance and reliability.
Alliance Memory announces NOR flash agreement with Micron
Alliance Memory is now an authorised reseller for Micron Technology’s discontinued M29F 5V parallel NOR Flash devices.
SMART Modular’s DDR4 NVDIMMs reach new speed threshold
SMART Modular Technologies has announced new higher density 16GB and 32GB NVDIMMs which run at DDR4-3200 high speed bus rates. These products, incorporating Micron advanced DDR4 DRAM technology in combination with SMART’s high-speed PCB designs, significantly improve signal integrity, resulting in broader design margins even at the highest DDR4 bus speeds.
Fast discrete graphics memory From Micron powers NVIDIA
Micron Technology has announced a fast discrete graphics memory solution, GDDR6X, the first to power system bandwidth up to 1 terabyte per second (TB/s). Working with NVIDIA, Micron debuted GDDR6X in the new NVIDIA GeForce RTX 3090 and GeForce RTX 3080 graphics processing units (GPUs), which are tailored to support the fast speeds that immersive, high-performance gaming applications demand.

EcoXiP Octal xSPI NVM for RZ/A2M microprocessor
Dialog Semiconductor has announced that its EcoXiP octal xSPI non-volatile memory (NVM) which was added to Dialog’s portfolio through its recent acquisition of Adesto Technologies, is now optimised to be used with Renesas’ RZ/A2M Arm-based microprocessors (MPUs).
What changes in DDR4 vs DDR5 DIMMs?
The top six most significant specification advances made in the transition from DDR4 to DDR5 DIMMs are shown in Table 1 below.
What are the DDR5 design challenges?
Changes in DDR5 have introduced a number of design considerations dealing with higher speeds and lower voltages – raising a new round of signal integrity challenges. Designers will need to ensure that motherboards and DIMMs can handle the higher signal speeds. When performing system-level simulations, signal integrity at all DRAM locations need to be checked.
