Evolution of embedded flash memory technology for MCU

Embedded flash memory technology has undergone tremendous growth of demands with various performance requirements driven by expanded applications of MCU (Micro Controller Unit) products. High temperature operations with highest reliability for auto-motive applications, very low power embedded EEPROM functions for smart-cards, and ultra low-voltage operations for medical applications are driving factors in developing embedded flash technologies. Together with evolving memory cell technology, resolving performance/power trade-offs by developing dedicated design platforms with optimized eFlash technology, memory interface & bus designs, and the whole chip design methodologies, has realized advanced MCU products line-ups by split-gate MONOS flash technology with a wide range of applied products including auto-motive and security applications.
