Resilient storage for demanding applications

Embedded NVM

Each of our technology platforms comes with a broad offering of proven, embedded non-volatile memory (e-NVM) solutions that support all possible customer applications.

Best-in-class reliability 

Most of our e-NVM offering is qualified and proven in the field according to the most stringent automotive standards. Compared to other solutions on the market, it provides best-in-class resiliency and zero-defect operation even under the most demanding conditions. We have achieved this feat by selecting the most appropriate technologies, like SONOS flash, and mastering the whole design-to-manufacturing process, in particular to serve the automotive market.

Facilitating customer’s product management

As the proprietor of both the technology platforms and the e-NVM IP design, we are in the right position to develop e-NVM solutions that either minimize or completely eliminate the need for additional process layers to the core module. This enables our customers to benefit from extensive IP reuse across different product families, helping to optimize product portfolio and roadmap management.

Design flexibility

The availability of flexible memory cut selection, through compilers or sliceable elementary cells, enables our customers to smoothly pick and accommodate the most suitable e-NVM solution for their design, optimizing footprint and die cost. The required design documentation is made available in real time and is compatible with all major EDA tools, making the process of embedding the IP into the customer’s product a seamless, plug-and-play task.

One-stop shop

Our full in-house expertise of the NVM development process, which encompasses memory design, qualification, testing and continuous customer support, allows us to offer joint development of customer-specific solutions when required.

Applications

  • Circuit trimming, configuration and traceability

    Embedded OTP and latches

    Trimming solutions enable required presets for analog design, or provide additional memory space to record a small amount of specific data, ranging from part identification and traceability to basic system configuration.
    Solutions are compiler-based or sliceable in order to seamlessly fit our customer’s design.

  • Data storage and data-logging 

    Embedded EEPROM and NVRAM

    EEPROM and NVRAM are extensively used for intensive data rewriting purposes, such as storing data logs from the field, enabling more flexibility in code programming, supporting data security or managing faster access time and low-power requirements. The compiler-based approach further optimizes footprint and die cost when embedding the solution in the customer’s chip.
