Progressing Memory Capacity: Transition to 3D NOR Flash Technology
In the rapidly evolving landscape of artificial intelligence (AI), Internet of Things (IoT), and edge computing, the demand for high-performance memory solutions is escalating. Enter 3D NOR flash, a next-generation technology poised to address these needs by offering significant advantages over traditional 2D NOR flash.
3D NOR flash delivers a 200-MHz double transfer rate (DTR), ensuring high-speed data transfer for AI processing and real-time analytics. This technology is designed to meet the evolving memory needs of AI, IoT, and edge computing by offering higher density, faster access times, enhanced reliability, improved security, and reduced power consumption.
## Advantages of 3D NOR Flash
### Higher Density and Scalability
3D NOR flash achieves densities up to 8 times greater than 2D NOR, allowing for more storage on a single die. For instance, Macronix has developed a 3D NOR architecture that can deliver 4 Gb on a single die, significantly improving storage capacity without increasing the footprint. This higher density is particularly beneficial for applications in AI, IoT, and edge computing, where both space and power efficiency are crucial.
### Faster Access Times
The faster access times offered by 3D NOR flash are essential for applications requiring quick data access, such as AI-driven solutions and real-time data processing in IoT devices. The improved performance reduces latency, thereby improving boot performance, which is an essential feature for applications that need near-instantaneous access to stored data.
### Enhanced Reliability and Security
The architecture of 3D NOR flash enhances data integrity, making it suitable for industries where reliability is paramount, such as automotive and industrial sectors. With fewer devices needed, 3D NOR reduces the overall attack surface, improving security compared to setups requiring multiple storage devices like eMMC and/or NAND.
### Power Efficiency
By reducing the need for data transfer between separate memory devices, 3D NOR flash improves power efficiency, which is crucial for battery-powered IoT devices and edge computing applications.
## Comparison with Traditional 2D NOR Flash
Traditional 2D NOR flash is limited by its planar architecture, which constrains scalability and makes it challenging to meet growing demands for higher densities and lower latency. 3D NOR flash addresses these limitations by providing higher storage capacities and faster access times, making it more suitable for advanced applications in AI, IoT, and edge computing.
Companies such as Macronix expect to begin sampling 3D NOR flash chips in the second half of 2026, with full-scale production likely in 2027. Macronix plans to leverage existing manufacturing facilities and processes used for developing 2D NOR to usher in the next generation of flash memory quickly and efficiently.
In conclusion, 3D NOR flash is better equipped to handle the evolving memory needs of AI, IoT, and edge computing by offering higher density, faster access times, enhanced reliability, improved security, and reduced power consumption compared to traditional 2D NOR flash. This technology is expected to set the stage for the continued push of innovation in general NVM and serve as a key driver of the next wave of memory advances.
