Memory is not just a number or a storage space in many systems, but can often prove critical to the reliable, long-term performance of those systems. Choosing embedded memory for different systems can be a key part of the design process, especially for systems that must endure hostile environments and wide temperature ranges. Fortunately, a six-page white paper from a long-time supplier of portable memory keys, Datakey Electronics (www.datakeyelectronics.com), can help when adding reliable memory solutions to military, industrial, medical, and commercial applications. The white paper, “How to Choose Portable Memory for Embedded Systems: Comparing Consumer and OEM Memory Devices,” reviews a wide range of consumer and industrial-level products, including SD cards and USB flash drives. Copies of the whitepaper are available for free download from: http://www.datakeyelectronics.com/portable-memory-choices-white-paper.html.
