Researchers at Switzerland's École Polytechnique Fédérale de Lausanne (EPFL) have developed a device that combines ultra-thin two-dimensional semiconductors and ferroelectric materials, with the goal of integrating digital logic and brain-inspired analog operations.

The semiconductors enable ultra-efficient digital processors, while the use of ferroelectric materials allows for the simultaneous processing and storage of memory.

EPFL's Adrian Ionescu said, "The research marks the first-ever co-integration of von Neumann logic circuits and neuromorphic functionalities, charting an exciting course toward the creation of innovative computing architectures characterized by exceptionally low power consumption and hitherto unexplored capabilities of building neuromorphic functions combined with digital information processing."
