SST and UMC Announce Qualification of Embedded SuperFlash®

SST and UMC Announce Qualification of Embedded SuperFlash® Technology on 40 nm CMOS Process

CHANDLER, Ariz., April 30, 2018 (GLOBE NEWSWIRE) -- The amount of data processed in Internet of Things (IoT) applications continues to increase, making low power and high density paramount to system designers. Many IC designers are turning to single-chip solutions to implement these features, saving total system costs by combining digital, analog, RF, microcontroller (MCU) and embedded Flash memory on a monolithic device. To meet these needs, Microchip Technology Inc. (NASDAQ: MCHP) subsidiary Silicon Storage Technology (SST), and United Microelectronics Corporation (NYSE: UMC) (TWSE:2303), a leading global semiconductor foundry, today announced the full qualification and availability of SST’s embedded SuperFlash non-volatile memory on UMC’s 40 nm CMOS platform. The 40 nm process features a more than 20 percent reduction in embedded Flash cell size and a 20-to-30 percent reduction in macro area over their 55 nm process.

The high endurance of embedded SuperFlash IP offers System on a Chip (SoC) customers extensive reliability and design flexibility combined with reduced power usage. SST’s SuperFlash non-volatile memory technology is qualified for a minimum of 100,000 cycles, underscoring the technology’s reliability. Ideal for edge computing in IoT devices, SST embedded SuperFlash technology features power benefits that derive from low-power standby and read operations, with core supply as low as 0.81V. SuperFlash also secures applications with code maintained on chip, which is the first step in preventing illegal access through hardware and software attacks.

“The 40 nm qualification represents another milestone in our partnership with UMC,” said Vipin Tiwari, director of worldwide business development and marketing for SST, a wholly owned subsidiary of Microchip. “SuperFlash technology continues to be the most reliable embedded Flash memory in the semiconductor industry, providing customers across broad markets the low-power, high-density features their products depend on.”

“With the positive response and success from customers who used SST’s 55 nm SuperFlash technology, we are pleased to offer our customers another process platform with characteristics that fit a range of IoT applications,” said Wenchi Ting, associate vice president of Specialty Technology division at UMC. “The addition of the fully qualified 40 nm SST SuperFlash will further enrich our IP portfolio of high-quality embedded memory solutions.”

SST’s SuperFlash technology complements UMC’s embedded memory portfolio with high density and low-power IP. Combined with SST’s inherent technology reliability, UMC’s flexible capacity and high-yield maturity for its 55 nm and 40 nm platform provide foundry customers the manufacturing support needed to build a range of product applications.

To date, more than 80 billion units have shipped with SST’s embedded SuperFlash technology. SuperFlash technology is based on a proprietary split-gate Flash memory cell with the following capabilities:

Low-power program, erase and read operations
High performance with fast read access
Good scalability from 1 µm technology node to 28 nm technology node
High endurance cycling up to 500,000 cycles
Excellent data retention of over 20 years
Good performance at high temperature for automotive-grade applications
Immunity to Stress-Induced Leakage Current (SILC)
