Introduction DRAM memory is an essential component of products such as computers and smartphones, and it is an indispensable “part” of digital infrastructure. This article provides a detailed overview of the development history of memory chips over the years. On September 12, 1958, Jack Kilby from Texas Instruments successfully integrated five components, including germanium transistors, … Read more
Classification of Semiconductor Products Semiconductors have conductivity properties that lie between conductors and insulators. Although semiconductors were recognized by academia only in the 1930s, with the rapid advancements in science and technology, they are now closely related to our lives, such as in computers, mobile phones, lighting, refrigerators, air conditioners, and power converters, all of … Read more
Modern vehicles are increasingly equipped with electronic devices, necessitating good design practices to meet the requirements of major electromagnetic compatibility (EMC) standards. The rising levels of integration have also led automotive designers to urgently seek Application-Specific Integrated Circuits (ASICs) and Application-Specific Standard Products (ASSPs) that can replace multiple discrete components. This article discusses some of … Read more
Click the title below “National New South” for quick attention Source: Shuo Xin Yu In the 1930s, Zhang Xilun, a student from Hebei, graduated from the first mining university in China, Jiaozuo Institute of Technology. As a rare talent specialized in metallurgy, he was hired by a steel plant in Shanghai. After the outbreak of … Read more
In Silicon Valley Legend I: Shockley and the Transistor, we told the story of the birth of the transistor and Shockley’s journey to Silicon Valley to start a business, as well as the origins of Fairchild Semiconductor. We also introduced how this pioneering company obtained funding, intertwined with the enmity between Shockley and others. In … Read more
If you look at a printed circuit board (PCB), you will easily find many symbols on these boards. These symbols represent the designations of electronic components, which can help engineers quickly identify and manage components during the design and production stages, as well as improve maintenance efficiency. So, how can we distinguish the component designations … Read more
Did you know? The smartphones, computers, and even smart refrigerators we use today all contain a “magic box”—the semiconductor chip. This tiny component, no larger than a fingernail, powers the entire world. Today, let’s discuss how this “magic box” evolved from obscure research in laboratories to become the heart of global technology. 1. Vacuum Tubes: … Read more
The semiconductor industry is the cornerstone of modern information society, characterized by a highly complex supply chain with clear specialization, covering the complete chain from raw materials to end applications. The semiconductor supply chain, from upstream (materials and equipment), midstream (design, manufacturing, packaging, and testing) to downstream (applications and terminals), relies on continuous technological innovation. … Read more
Hello everyone! I am the strategic logic deducer, Hongling Road. First, I would like to thank all my fans for their continued support. However, I have been very busy these days and haven’t had time to produce any public works. Recently, I have been deeply studying commercial aerospace, so I haven’t had time to write. … Read more
