(Source: Semiconductor Industry Observation) Introduction USB4™ is a new connectivity standard established by the USB Implementers Forum (USB-IF). USB4 supports multiple high-speed interface protocols, including USB4, DisplayPort, PCI Express, and Thunderbolt 3, enabling efficient data transfer, power delivery, and high-resolution video through a single USB Type-C cable. USB4 achieves speeds of up to 40Gbps, which … Read more
SD storage cards have been improving over time, especially with the introduction of UFS, which has significantly increased their speed. However, overall, they still remain relatively slow. Now, the SD Association (SDA) is preparing a revolutionary transformation to turn them into mini SSDs. In fact, this plan was disclosed by the SDA during the flash … Read more
