SST and UMC Announce Qualification of Embedded SuperFlash® Technology on 40 nm CMOS Process
May 02 2018 - 8:06AM
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)
