Development of Industry’s First 40nm Embedded Flash Memory for Automotive Applications
Renesas has announced the development of industry’s first 40nm embedded flash memory technology for use in automotive real-time applications. Along with that company will release a world’s first 40nm embedded flash MCUs (Microcontrollers) for automotive applications using the technology with availability of samples by autumn of 2012. The company uses the MONOS (metal oxide nitride oxide silicon) technology to embed the flash memory, a proven and scalable technology, which has also been used before at higher scales.
The new 40nm flash feature distinguishing characteristics in regard to three critical parameters which are data retention, program/erase cycle endurance and programming time. The new technology guarantees data retention of 20 years where it can be read from up to 170 degrees Celsius junction temperature. In addition to this the code flash supports read speed of 120 MHz.
