From DDR3, DDR4 and DDR5, learn the progression of the technology, how tests have evolved, and the test equipment that can help combat challenges.
Cloud, networking, enterprise, high-performance computing, big data, and artificial intelligence are propelling the development of double data rate (DDR) memory chip technology. Demand for lower power requirements, higher density for more memory storage, and faster transfer speeds are constant. Servers drive the demand for next-generation DDR. Consumers benefit when existing and legacy generations economize and become affordable. As dynamic random-access memory (DRAM) decreases in price, it makes its way into our PCs and laptops. To accommodate these requirements, standardization body JEDEC (Joint Electron Device Engineering Council) released the DDR5 synchronous dynamic random access memory (SDRAM) standard in July 2020. Starting in mid-2021, JEDEC expects to start seeing DDR5 devices emerge as manufacturers confirm hardware.
Test Challenges — Signal integrity and data corruption issues can make testing DDR designs problematic. Understanding the issues is the first step toward solving them.
