AMI Semiconductor Integrates Flash Memory with SmartPower Technology to Deliver True SoC Designs
Integrated HiMOS™ NVM Flash gives cost and space savings in a wide range of applications
Pocatello, IdahoAMI Semiconductor, a designer and manufacturer of state-of-the-art integrated mixed-signal and structured digital products for the automotive, medical and industrial markets, today announced that it is now able to offer Flash memory embedded in its high-voltage CMOS based system-on-chip designs. The integration of HiMOS non-volatile memory (NVM) with the company’s established I3T80 SmartPower technology allows designers to develop fully integrated solutions that achieve important cost and space savings plus performance benefits for their applications.
The inclusion of Flash memory requires only three additional mask layers to the I3T80 base technology mask set. The small number of extra layers that are needed helps ensure designs are as cost effective as possible.
Available Flash memory sizes range up to 64kBytes with 100 erase cycles for code storage, and up to 512 bytes and 10,000 erase cycles for data storage.
With an operating temperature range of –40C to +125C, I3T80 SoC designs with embedded Flash are well suited to applications in the most demanding environments. Further key features of NVM Flash include a sector and multiple sector erase time of 0.5s and page program in 20ms (32 pages per sector). Random access read time is 100ns for either 8- or 16-bit words. The memory can retain data for up to 10 years and has automotive qualification to AEC-Q100.
AMI Semiconductor’s Flash memory has been developed in conjunction with IMEC, Europe’s leading independent research centre in nanoelectronics and nanotechnology, and uses IMEC’s High Injection MOS (HiMOS) split gate technology.
I3T80 enables the delivery of 0.35mm CMOS-based SmartPower SoC solutions for voltages up to 80V. The technology allows the integration of complex digital circuitry, embedded microprocessors and high voltage functionality on a single IC and is suitable for automotive, medical, industrial, and other high-voltage designs.
AMIS supports the supply of its SoCs with integrated NVM Flash for the lifetime of a project; in automotive and industrial applications this can be 10 years or more. This protects against the risk of needing to periodically re-qualify a design due to the phasing out of current technology in favor of newer approaches, a problem that often occurs when using stand-alone NVM.
