Silicon Storage Technology, Inc. (SST) is a Sunnyvale, California, USA, technology company producing non-volatile memory devices and related products. SST supplies of NOR flash and other integrated circuits for high-volume applications.
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 trade show, SST introduced the 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 its headquarters to 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. The company had its initial public offering November 21, 1995, trading on the NASDAQ market under the symbol SSTI. Analytical models of SuperFlash were published. A five year licensing agreement was announced in January 1999 with Acer Inc.. A 1997 lawsuit filed by Intel was settled in May 1999 after mediation.
During the next 10 years, SST introduced low- to medium density memory products and expanded their applications beyond PCs. In 2004, SST began to diversify beyond flash memory products, targeting consumer and industrial products with embedded solid-state data storage and RF wireless communication. In September 2004 SST purchased a majority stake in Emosyn, which designed products for SIM cards. In October it announced the acquisition of G-Plus, based in Santa Monica, California.
SST had its stock option grant practices investigated by the US Securities and Exchange Commission, ending in June 2008. It determined it needed to restate earnings, and was giving a de-listing notice by NASDAQ for filing late reports from 2006 through 2007. Business slowed in the Great Recession.The company announced a loss on reduced revenues, reducing its workforce by 17% in December 2008.
In November 2009, Technology Resource Holdings offered to acquire the company for about $200 million, but a group of shareholders thought it was undervalued. Starting in February 2010, private equity firm Cerberus Capital Management and public company Microchip Technology both made offers to acquire SST.  In April 2010, Microchip completed the acquisition for about $292 million. Microchip sold several SST flash memory assets to Greenliant Systems (founded by Yeh) in May that year.
