There are multiple memory companies on the market, but only a few true memory manufacturing companies. When researching different memory brands, you may run across companies that claim to be memory manufacturers, when they're really just module assemblers. How these companies work is that they purchase pre-manufactured parts (such as DRAM chips and printed circuit board) from true memory manufacturers, and then assemble these components to “manufacture” a module with their label on it.
True memory manufacturing involves a much higher level of technical expertise and quality control, and involves everything from selecting choice silicone to functional module testing. True memory manufacturers design, produce, and test components and modules at all stages of production. Memory modules consist of two pieces: DRAM semiconductor chips that store data, and printed circuit board (PCB), which connects the memory chips to the rest of the computer. There are only a handful of semiconductor manufacturers with the capability to produce DRAM chips, and they are Micron (Crucial), Samsung, and Hynix.
Since Crucial is a brand of Micron, one of the largest memory and flash storage manufacturers in the world, our products are backed by some of the most rigorous quality standards in the industry. Unlike some memory and SSD companies, we are vertically integrated and we sell the same products that we produce for the world's leading computer manufacturers. For you, this means that the same memory you buy from us is often the same memory that was installed in your system when you bought it.
Because we make our products for the leading computer manufacturers, we work closely with them to ensure optimal compatibility and performance. Every single module we sell is compliant with JEDEC industry standards and 100% of our modules have been tested at the component, module, and functional levels. Likewise, the SSDs that we manufacture have passed hundreds of SSD qualification tests and over a thousand hours of prerelease validation testing. If a Crucial product doesn't meet our rigorous standards, then it doesn't leave our doors. That's quality you can depend on – don't settle for anything less.
