What is memory JEDEC Compliance

JEDEC is an organization made up of 300 plus member companies from all over the world. They consist of memory vendor companies like Micron, Samsung, Infineon, Hynix and Nanya. Memory module manufacturers like Kingston, Smart Modular, and Wintec. Connector manufacturers like Molex, and Foxconn. Memory user companies like Sun Micro, Silicon Graphics, and HP. Tester companies like Tektronix, Agilent and CST. Chipset companies like Nvidia, Via and SIS.

All these companies realize that the only way to have the best price for memory and its associated system is to promote one mainstream technology for the entire industry. Therefore, these companies get together 4 times a year all into one room with their difference set aside and to concentrate on formulating a standard memory that the industry can accept. The result is robust design memory devices and modules that will work reliably in the computer systems. This standard becomes the minimum requirement for the memory market. It is recognized by all OEM computer manufacturers and is supported by the entire industry.

Member companies worked together on specification, simulation, prototyping, example design, test parameters and system validations. A guideline is set down so that all JEDEC compatible memories will be functionally inter-changeable with similar performances.

Advantages

Non-JEDEC compliance memory modules have been flooding the market resulting in unstable computer systems and confusion. System integrators and consumer are easily tempted by the short-term cost saving without knowing its long-term consequence. This article investigates the design process in JEDEC Raw cards. It highlights the details on proper memory module design. Whether it is clock net, stub length, termination resistor, or impedance control, they all involve thousands of hours of simulation and engineering. The resulting Gerbers are offered free of charge to you. It might make you think differently next time you pick up a memory module.
