Fudan University Researchers Develop Ultra-Fast ‘Pox’ Flash Memory
SHANGHAI (AP) — Researchers at Fudan University have announced teh growth of a novel non-volatile flash memory technology,dubbed “Pox,” boasting speeds previously unattainable for this type of storage. The new memory is capable of programming a single bit in just 400 picoseconds, equivalent to 0.0000000004 seconds, translating to 25 billion operations per second.
Speed Breakthrough
The findings, published in the journal Nature, indicate a critically important leap in non-volatile memory speed, rivaling that of the fastest volatile memory solutions. This advancement could establish a new benchmark for hardware used in artificial intelligence applications, which demand increasingly rapid data access.
Graphene Innovation
the research team, led by Professor Zhou Peng at the State Key laboratory of Integrated Chips and Systems, achieved this breakthrough by redesigning the basic physics of flash memory. they replaced conventional silicon channels with two-dimensional Dirac graphene, leveraging its superior charge transport capabilities. By optimizing the channel’s “Gaussian length,” the team created a two-dimensional “super-injection” affect, enabling a virtually unlimited influx of charge into the storage layer, overcoming previous injection bottlenecks.
Theoretical Limits Reached
Professor Zhou told the Xinhua news agency that artificial intelligence-driven process optimization allowed them to push non-volatile memory close to its theoretical performance limit, paving the way for future generations of high-speed flash memory.
comparison to Existing Technology
Co-author Liu Chunsen offered an analogy, comparing the advancement to moving from a USB drive capable of 1,000 wriet operations per second to a chip performing a billion operations in the same timeframe.The previous record for non-volatile flash memory programming speed was approximately two million operations per second.
Advantages of ‘Pox’ Memory
The non-volatile nature of “pox” memory allows it to retain data without requiring a constant power supply, a critical feature for next-generation and battery-powered devices. The combination of extremely low energy consumption and picosecond-level writing speeds could alleviate memory bottlenecks in AI hardware for both inference and training. Currently, data transfer, rather than arithmetic calculations, is a primary factor in energy consumption for thes applications.
Industry Impact
Experts suggest this development represents a “completely original mechanism” with the potential to disrupt the flash memory landscape, a key component of the global semiconductor strategy due to its cost-effectiveness and scalability.
Potential Applications
Large-scale production of “Pox”-based memory could potentially replace the expensive and bulky high-speed SRAM cache in AI chips, considerably reducing space requirements and energy consumption.This could lead to devices like laptops and smartphones with near-instantaneous startup times and lower power consumption. It could also support database systems capable of storing entire working datasets in persistent RAM.
China’s Semiconductor Ambitions
This technology could bolster China’s efforts to secure a leading position in core chip technologies. While the research team has not yet released data regarding the memory’s lifespan or manufacturing yield, the use of a graphene channel suggests compatibility with two-dimensional material processing techniques currently being explored by major manufacturers worldwide. Professor Zhou emphasized that this revelation has the potential to reshape storage technology,drive industrial upgrades,and unlock new submission possibilities.
Future Development
Fudan University engineers are currently focused on expanding the cell architecture and creating array demonstrations. While no commercial partnerships have been announced, Chinese foundries are reportedly accelerating the integration of two-dimensional materials with traditional CMOS production lines.
