Innovations in Ferroelectric Memory Technology

At the 2026 IEEE / JSAP symposium on VLSI Technology & Circuits, imec has presented groundbreaking research in ferroelectric memory technologies, addressing the increasing demands for memory capacity due to AI workloads. As traditional memory technologies like DRAM and SRAM face scaling challenges, ferroelectric memory appears poised to bridge the gap, offering low-voltage operation and potential for high-density 3D integration.

Imec introduced two significant advancements: low-voltage ferroelectric capacitors targeted for DRAM-like applications and vertically stacked ferroelectric field-effect transistors (FeFETs) that promote compact memory architectures for next-generation AI systems. The ferroelectric capacitors operate at approximately 1.3 volts, showcasing strong remnant polarization (>40 μC/cm²) and high endurance (≥10¹³ cycles), essential attributes for efficient memory performance.

Complementarily, the demonstration of stacked IGZO-based FeFETs marks a step towards achieving high-density 3D memory. The introduction of a dual-gate design, featuring a back-gate, enhances erase efficiency—a critical limitation in FeFET technology. This innovative architecture emphasizes the potential of using oxide semiconductors in the development of next-gen memory solutions.

Imec’s multidisciplinary approach leverages shared materials and strategies across both technologies, allowing insights gained from ferroelectric capacitors to optimize FeFET devices. Techniques demonstrated in the 3D integration of FeFETs also pave the way for robust ferroelectric capacitor arrays, illustrating the interconnected benefits of these memory components.

This growth in memory technology is timely, as the semiconductor industry grapples with the limits of conventional memory, which struggles to meet the increasing demands of AI and data-intensive applications. The low-voltage capabilities of ferroelectric capacitors support energy-efficient designs, while advancements in FeFETs offer a promising path towards space-efficient memory configurations.

Attilio Belmonte and Maarten Rosmeulen, program directors at imec, highlighted the collaboration of materials science and advanced integration techniques as a way to address memory technology challenges. The dual focus on device optimization and the development of reliable, high-density 3D architectures is crucial as the demand for innovative memory solutions surges.

While these technologies remain in the research phase, they signify significant progress towards next-generation memory solutions intended to redefine data storage and access in an era driven by AI. Future endeavors will center on overcoming barriers related to endurance and reliability, while further optimizing performance metrics to bring these concepts closer to commercial viability.

Imec continues to be at the forefront of semiconductor innovation, with a wide-reaching impact across various industries. As the company explores the potential of ferroelectric memory technologies, it stands poised to play a key role in shaping the future landscape of data storage.
