Silicon Integrated Systems

Silicon Integrated Systems (SiS; ) is a company that designs and manufactures integrated circuits, chipsets and components related to Human-Machine Interfaces (HMI).SiS矽统科技. (n.d.). Silicon Integrated Systems Corp | SIS 矽統科技. https://www.sis.com/en-us The company was founded in 1987 in Hsinchu Science Park, Taiwan.

Business In the late 1990s, SiS made the decision to invest in their own chip fabrication facilities. At the end of 1999, SiS acquired Rise Technology and its mP6 x86 core technology.Carroll, Mark. SiS acquires Rise CPU technology , EE Times, 13 October 1999. Silicon Integrated Systems (SiS) acquired Hycon Technology on January 1, 2025. The acquisition involved SiS issuing 0.8713 shares for every Hycon share, totaling 27,755,080 shares.

Mainboard chipsets

One of the most famous chipsets produced by SiS was the late 486-age chipset 496/497 which supported PCI bus among older ISA- and VLB-buses. Mainboards using this chipset and equipped with CPUs such as the Intel 80486DX4, AMD 5x86 or Cyrix Cx5x86 processors had performance and compatibility comparable with early Intel Pentium systems in addition to a lower price.

After this late success, SiS continued positioning itself as a budget chipset producer. The company emphasized high integration to minimize the cost to implement their solutions. As such, SiS one-chip mainboard chipsets that included integrated video, such as the Socket 7-based SiS 5596, SiS 5598, and SiS 530 along with the Slot 1-based SiS 620. These were some of the first PC chipsets with such high integration. They allowed entire system solutions to be built with just a mainboard, system RAM, and a CPU.

Includes integrated UDMA66 IDE controller. mainboards using the SiS 530 were positioned as cheap office platforms and paired often with low-cost chips from Intel competitors, such as the AMD K6 series or Cyrix 6x86. The graphics controller had Direct3D 6.0 and OpenGL support, although it was a very low-performance product for 3D acceleration.Masrani, P.

Southbridge chips

Paired with later SiS chipsets, such as the 661GX/761GX, which adopt a standard two-chip chipset design (instead of single-chip, like the older SiS 630/730 series chipsets). SiS southbridges can handle IDE, LAN (accompanied by a PHY chip), audio (with an AC'97 codec), along with other types of I/O. SiS' proprietary MuTIOL interconnect connects the southbridge chip to the northbridge, which contains the RAM controller (for chipsets targeted at Intel platforms) and interfaces with the CPU.
