GigaDevice offers one of the broadest non-volatile memory portfolios in the market, covering Serial NOR Flash, Octal NOR Flash, SPI NAND Flash, Automotive Flash, WLCSP Flash and I²C EEPROM products. Solutions range from small configuration memories through to high-density storage devices for embedded Linux, networking, industrial and automotive systems.

Serial NOR Flash
The most widely used flash family for code storage and boot memory.
Typical applications
- Microcontroller firmware storage
- Consumer electronics
- Industrial controllers
- IoT devices
- Networking equipment

The current recommendation is to focus on 55nm E/F series and 45nm H/J series products for new designs. Older 65nm C/D versions are gradually being phased out and should only be considered for existing designs.
Available technologies
- 65nm (Legacy generation)
- 55nm (Mainstream generation)
- 45nm (Latest generation)

45nm NOR Flash
The newest NOR Flash generation and the primary focus for future designs. Available in both standard Quad SPI and high-performance Octal SPI variants.
Key benefits
- Improved reliability
- Higher performance
- ECC support
- Advanced Quad SPI and Octal SPI families
- Designed for long-term product roadmaps

SPI NAND Flash
High-density, cost-effective storage for large data requirements. The newer 24nm family provides improved performance and reliability.
Typical applications
- Embedded Linux systems
- Data logging
- Smart gateways
- Networking products
- AI and edge computing
Technology generations
- 38nm (legacy products)
- 24nm (current mainstream products)

Octal NOR Flash
Designed for applications requiring very fast code execution and boot times. Provides significantly higher bandwidth than traditional Quad SPI devices and is becoming increasingly common in next-generation embedded platforms.
Typical applications
- Application processors
- Embedded Linux
- AI edge devices
- Advanced HMI systems
- Networking equipment

Automotive Flash
Automotive-qualified versions of NOR and NAND flash designed for harsh operating environments. Available with AEC-Q100 qualification and extended temperature ranges. Current automotive designs should focus on 55nm and 45nm NOR technologies.
Typical applications
- Instrument clusters
- Telematics
- ADAS
- Body control modules
- Automotive gateways
