DDR5 modules enhance stability in industrial applications
DDR modules with enhanced endurance and stability for industrial applications have been released by Smart Modular Technologies. The DRAM modules combine DDR5 technology with the company’s rigorous test processes.
The stringent testing processes ensure reliable operation at industrial-grade temperatures (-40 to +85 degrees C). Customised Smart test programs and test flows combined with specialised burn-in equipment are used to screen out DRAM components that are likely to fail under temperature stress. As a result, the modules exhibit some of the lowest defects parts per million (DPPM) rates in the industry, says Smart. The industrial-grade modules are 100 per cent system tested at high speeds, starting with a cold boot at -40 degrees C and ramping to +85 degrees C ambient operation. High-utilisation customised testing software stresses all cells in the DRAM through the complete temperature cycle for a thorough test process.
“Smart applies all of its proven industrial-grade feature sets, including burn-in, conformal coating, anti-sulphur resisters and other processes to these new modules,” said Arthur Sainio, director of product marketing at Smart Modular Technologies. “These added features ensure that our DDR5 modules can operate reliably in the harshest operating environments,” he added.
For additional reliability, Smart also offers a locking retention device, the ARC (Anti-vibration Retention Clamp), which is designed to secure memory modules used in operating environments that require maximum stabilisation in the field.
Smart DDR5 industrial-grade modules provide twice the performance of DDR4 and also improve power efficiency via the on-DIMM 12V voltage regulator (PMIC) and dual-channel DIMM topology for higher channel efficiency. The modules are suitable for a wide variety of applications, including single board computers (SBCs) used in industrial and defence applications, base stations and telecomms equipment exposed to outdoor elements, and densely configured computing applications with limited airflow.
The DDR5 industrial-grade modules include unbuffered and registered DIMMs in 16, 32 and 64Gbyte densities, and unbuffered and ECC SODIMMs in 8.0, 16 and 32Gbyte densities.
