SST and UMC Qualify Flash Tech on 40-nm Process

Microchip Technology subsidiary Silicon Storage Technology (SST) and United Microelectronics Corporation (UMC) have 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 0.81 V. SuperFlash also secures applications with code maintained on chip, which is the first step in preventing illegal access through hardware and software attacks.

 

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 provides 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)
