Wide temperature DRAM modules operate within the range of −40°C to 85°C. These modules are designed to tackle harsh environmental conditions seen by applications such as in-vehicle, factories, networking, and outdoor kiosks as well as the surveillance and defense markets.
The wide temperature specifications are based on the JEDEC standards for DRAM integrated circuits (IC), with the JEDEC Standard 21C outlining the specifications for standard DRAM modules. These outline the basic specifications of wide temperature DRAM and together with testing procedures and quality control it lays the groundwork for how to design industrial-grade, wide temperature memory.
