GlobalFoundries and Microchip Technology, via its Silicon Storage Technology® (SST®) subsidiary, have announced the immediate release to production of the SST ESF3 third-generation embedded SuperFlash technology non-volatile memory (NVM) in the GF 28SLPe foundry process.

GF has established a new industry benchmark for implementing SST’s widely deployed ESF3 SuperFlash memory technology. This implementation delivers the following capabilities and benefits:

  1. Lowest cost 28-nm HKMG ESF3 solution with only 10 masks added, including true 5-V IO CMOS devices.
  2. Highly competitive SST ESF3 bit cell size of less than 0.05 micron squared.
  3. Operating temperature rating of −40°C to 125°C.
  4. Sub-25 nanosecond read access times, 10-microsecond program times and four millisecond erase times.
  5. Endurance exceeding 100,000 program/erase cycles.
  6. No impact to design flows using GF 28SLPe platform-qualified IP (EG flow).
  7. Immediate availability of off-the-shelf macros from four megabits (Mb) to 32 Mb.
  8. Access to custom macro design support from SST or GF.

Use cases for embedded flash memory are exploding with the drive for increased intelligence at the edge. Embedded memory for secure code storage, over-the-air-updates and enhanced functionality is on the rise in a wide range of applications in home and industrial IoT as well as smart mobile devices. Innovative platforms are required to meet these needs.

“GF is proud to partner with SST to develop, qualify and release to production this impressive embedded NVM on our robust 28SLPe platform,” said Mike Hogan, chief business unit officer at GF. “Customers are finding this combination of high performance, excellent reliability, IP availability and cost effectiveness to be ideal for advanced MCUs, complex smart cards and IoT chips for consumer and industrial products.”

“SST and GF have partnered closely over the last decade to integrate and productize SST’s industry-standard ESF1 and ESF3 embedded Flash memory technologies into GF’s 130-nm BCD, 55-nm, 40-nm, and now 28-nm foundry platforms,” added Mark Reiten, vice president of SST, Microchip’s licensing business unit.
