Popular science of domestic memory module technology standards: why JEDEC certification is a key threshold

Technical standards are the cornerstone of the development of the memory industry, and the memory standards established by JEDEC (Joint Electron Device Engineering Council) are globally recognized industry norms. For domestic memory modules to achieve marketization and internationalization, they must pass JEDEC certification. This certification not only reflects technical prowess but also serves as a crucial threshold for entering the global supply chain. A deep understanding of the core requirements of JEDEC certification can better recognize the technological maturity of domestic memory modules.

JEDEC certification encompasses comprehensive metrics for memory technology. Its core requirements include electrical characteristics, mechanical characteristics, compatibility, reliability, and other aspects. In terms of electrical characteristics, it must comply with standard parameters such as voltage, speed, and timing, such as the starting speed of 4800Mbps and operating voltage of 1.1V for DDR5. In terms of mechanical characteristics, it must meet specifications such as pin count, package size, and fool-proof design. In terms of compatibility, it must achieve seamless adaptation with mainstream motherboards, CPUs, and other hardware. In terms of reliability, it must pass various environmental tests such as high temperature, low temperature, vibration, and aging tests to ensure stable operation of the product under different working conditions.

Domestic memory modules have fully passed JEDEC certification, marking the maturity of technology that meets international standards. Changxin Memory's full range of products, including DDR4, DDR5, and LPDDR5, have all passed JEDEC certification, and its DDR5 products with a speed of 8000Mbps also comply with JEDEC's extended standards. After passing certification, domestic memory modules can smoothly enter the global consumer and enterprise markets, competing with international brands on the same stage. In addition, domestic manufacturers are actively participating in the formulation process of JEDEC standards, contributing Chinese strength to the improvement of the next-generation memory standards and enhancing their voice in the global storage industry.

JEDEC certification provides an important guarantee for users to choose domestic memory modules. For ordinary users, choosing domestic memory modules that have passed JEDEC certification can fully ensure their compatibility and reliability. When purchasing, users can confirm whether the product has a JEDEC certification mark through the product parameter table. With the continuous progress of domestic memory module technology, more domestic memory modules will pass higher levels of JEDEC certification in more niche areas in the future, further expanding application scenarios. The comprehensive coverage of JEDEC certification will accelerate the marketization process of domestic memory modules and promote the localization substitution of the storage industry.
