Embedded Non-Volatile Memory IP for Mobile Markets

1-Mobile

Mobile devices are the fastest growing market segments, driven by convenience and innovative applications. Embedded non-volatile memory (NVM) is used as code storage for the baseband SoC, and for trimming and calibration of the power amplifiers and RF receivers. It is also used to store security keys for data transfer and multimedia content protection. Key requirements are ultra-low power operation for maximum lifetime and secure data storage to prevent identity theft.  Typical non-volatile memory (NVM) capacities for mobile applications range from 64kbit to +4Mbit and targeting the latest process nodes, 16nm and below.
