Silicon Integrated Systems (SiS; Chinese: 矽統科技; pinyin: Xìtǒng Kējì) is a company that manufactures, among other things, motherboard chipsets. 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 that company's mP6 x86 core technology.[1]

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.

SiS 5598

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.

Pentium (Socket 4,5,7)

SiS LAN Chip SiS900

The SiS 530 (Sindbad) with SiS 5595 southbridge supported Socket 7, SDRAM 1.5GB max., a bus frequency from 66 MHz to 124 MHz, and can have from 2 to 8 MiB shared memory for an integrated AGP SiS 6306 2D/3D graphics controller. 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.[2]

SiS 540 (Spartan) integrates SiS 300 graphics controller.

Socket 370, Slot 1

Socket 478, Socket 775

SiS and ALi were the only two companies initially awarded licenses to produce third party chipsets for the Pentium 4. SiS developed the 648 chipset with this license (SiS 648 B Stepping supports Intel Hyper-Threading CPU on some motherboards like MSI 648 Max).[3]

SiS created a multimedia chipset for the Xbox 360.[17]

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 handle IDE, LAN (with MAC chip), audio (with CODEC chip), and other I/O connectivity. 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.

Graphics chipsets

Some cards contain a 3D graphics accelerator but it is only functional with the SiS's Proprietary Windows-only driver (the company does not provide documentation for others to write drivers). However, the Linux kernel includes a working third party driver that, while not supporting 3D gaming, makes the cards usable under Linux.
