超捷SST (Silicon Storage Technology, Inc.)总部设于加州森尼维耳市，超捷SST (Silicon Storage Technology, Inc.)以自有的超快闪技术，产销多种非挥发性内存解决方案，并广泛应用于数字消费性产品、网络、无线通讯与网络运算市场。超捷SST (Silicon Storage Technology, Inc.)是快闪存储器(Flash)技术的领导厂商，以自有的超快闪技术，产销多种非挥发性内存解决方案，并广泛应用于数字消费性产品、网络、无线通讯与网络运算市场。超捷SST (Silicon Storage Technology, Inc.)旗下产品包括高功能闪存、大容量快闪储存产品与整合单芯片闪存微控制器。

超捷SST (Silicon Storage Technology, Inc.)于2001年3月在中国成立子公司冠捷(SST China)，为中国设计业者提供嵌入式闪存的设计与制造服务，同时也在中国研发并销售闪存、Flash/RAM复合型产品(combo)及嵌入式控制器等产品 。

超捷SST (Silicon Storage Technology, Inc.)旗下产品包括高功能闪存组件、大容量快闪储存产品与整合单芯片闪存的8位微控制器。另外，超捷SST (Silicon Storage Technology, Inc.)亦授权超快闪技术给超捷全球各大合作厂商，以开发嵌入式应用产品。授权厂商包括IBM、摩托罗拉、国家半导体、NEC、冲电气工业、三星电子、三洋电机、Seiko Epson、台积电与华邦电子。台积电所提供的SuperFlash技术名为Emb-FLASH超捷SST (Silicon Storage Technology, Inc.)的超快闪技术属于NOR型分裂闸（split-gate）单元架构，其采用厚氧化物制程，并不需要过多生产步骤，即可生产出资料储存能力优越与高可靠度的低成本、非挥发性内存解决方案。分裂闸NOR 超快闪架构提供简单、富弹性的设计，适用于高效能、高可靠度、中或小尺寸、系统内或外程序与各种不同密度的单一CMOS兼容技术。

2010年Microchip与超捷SST(Silicon Storage Technology)达成收购协议，Microchip将以现金每股2.85美元收购SST，透过这项协议，Microchip可以取得SST的闪存技术以及专利，这些技术都是先进MCU的基础区块(Building block)，有助于Microchip进一步拓展MCU的技术层次。超捷SST (Silicon Storage Technology, Inc.)专攻于多种非挥发性内存产品的设计、制造与市场领域。在SuperFlash的技术层面下，其产品广泛的运用在数字消费、无线网络通讯、网络计算机市场等。 Microchip与许多MCU供货商都采用SST的技术，因此Microchip买下超捷SST (Silicon Storage Technology, Inc.)之后，将可以强化旗下产品线的技术研发。

Silicon Storage Technology, Inc. (SST), is the innovator of SuperFlash®, a highly reliable and versatile NOR Flash memory. SST, the leader in embedded flash memory, was founded in 1989, and went public in 1995. SST was acquired by Microchip Technology, Inc. in April 2010 as a wholly own subsidiary. SST focuses on licensing embedded NVM technology to Foundries, IDMs and Fabless companies.

Bing Yeh and a team of engineers developed a non-volatile memory technology company called "SuperFlash" for code or data storage in electronic systems and embedded memory for integrated logic circuits.

Non-volatile memory devices retain data without a continuous supply of power. Virtually every microprocessor or microcontroller-based electronic system requires non-volatile memory to store a basic instruction set critical to the operation of the system. Prior to 1989, read-only memory (ROM), UV-light erasable PROM (EPROM), electrically erasable PROM (EEPROM), and the then-emerging flash memory created a succession of increasingly useful non-volatile memory products for this purpose. However, these products lacked important features, or were too expensive, for some desirable applications.

At the 1992 Fall COMDEX show, SST introduced the world’s first single-board 30 MB 2.5” solid-state drive with standard hard-disk ATA interface and a 5 MB PC Card memory card with built-in controller and firmware. At that time, the company deemed there to be an inadequate market for the devices, and focused on the memory component business.

In 1993, SST moved to its current headquarters in Sunnyvale. That same year, SST introduced its first SuperFlash technology products, with lower costs and faster write speeds. By the end of 1995, more than 90% of the PC motherboards produced in Taiwan had adopted SST's 1 Mbit SuperFlash EEPROM product for the BIOS storage. SST went public on the NASDAQ market in November 1995.

During the next 10 years, SST introduced low- to medium density memory products and expanded their applications beyond PCs. By the end of 2006, SST and its licensees had shipped more than seven billion integrated circuits based on SuperFlash technology. SST products are now used by almost every major electronic system manufacturer and can be found in virtually every type of IT and consumer product.

In 2004, SST began an initiative to diversify beyond flash memory products, targeting consumer and industrial products with embedded solid-state data storage and RF wireless communication.

In 2010, SST was acquired by Microchip Technology, which sold several SST flash memory assets to Greenliant Systems in May that year.
