Benchmarking of FERAM-Based Memory System by Optimizing Ferroelectric Device Model 150 150
Author(s): Mohammad Adnaan, Saeideh Alinezhad Chamazcoti, Emil Karimov, Marie Garcia Bardon, Francky Catthoor, Jan van Houdt, Azad Naeemi

Abstract:

We present a framework for design technology co-optimization (DTCO) of the main memory system with one transistor-one capacitor (1T1C) ferroelectric random access memory (FERAM) as an alternative to dynamic random access memory (DRAM). We start with the ferroelectric capacitor device model and perform array-level memory circuit simulation. Then, we …

3-D Stacked HBM and Compute Accelerators for LLM: Optimizing Thermal Management and Power Delivery Efficiency

3-D Stacked HBM and Compute Accelerators for LLM: Optimizing Thermal Management and Power Delivery Efficiency 150 150
Author(s): Janak Sharda, Madison Manley, Jungyoun Kwak, Chinsung Park, Muhannad Bakir, Shimeng Yu

Abstract:

Advanced packaging is becoming essential for designing hardware accelerators for large language models (LLMs). Different architectures, such as 2.5-D integration of memory with logic, have been proposed; however, the bandwidth limits the throughput of the complete system. Recent works have proposed memory on logic systems, where high bandwidth memory (HBM) …

A 28-nm Computing-in-Memory Processor With Zig-Zag Backbone-Systolic CIM and Block-/Self-Gating CAM for NN/Recommendation Applications

A 28-nm Computing-in-Memory Processor With Zig-Zag Backbone-Systolic CIM and Block-/Self-Gating CAM for NN/Recommendation Applications 150 150
Author(s): Shengzhe Yan, Zhuoyu Dai, Zhaori Cong, Zeyu Guo, Yifan He, Wenyu Sun, Chunmeng Dou, Feng Zhang, Jinshan Yue, Yongpan Liu, Ming Liu

Abstract:

Computing-in-memory (CIM) chips have demonstrated promising energy efficiency for artificial intelligence (AI) applications such as neural networks (NNs), Transformer, and recommendation system (RecSys). However, several challenges still exist. First, a large gap between the macro and system-level CIM energy efficiency is observed. Second, several memory-dominate operations, such as embedding in …

A Fully-Dynamic Capacitive Touch Sensor With Tri-level Energy Recycling and Compressive Sensing Technique

A Fully-Dynamic Capacitive Touch Sensor With Tri-level Energy Recycling and Compressive Sensing Technique 150 150
Author(s): Xiangdong Feng, Zhiyu Wang, Haoyang Li, Jiaqing Li, Wei-Chin Lin, Xin Hu, Zhong Tang, Yuyan Liu, Qinwen Fan, Yuxuan Luo, Bo Zhao

Abstract:

Capacitive touch screens have become the dominant user interface over the past decade. Achieving high framerates with low power consumption remains a critical design goal for touch systems. The conventional charge-recycling technique reduces driving power by 64%, but it relies on off-chip capacitors. To address this issue, we propose a tri-level …

Reference-Load Sharing Scheme: An Area- and Energy-Efficient Nonvolatile Register Design Using MTJ Devices

Reference-Load Sharing Scheme: An Area- and Energy-Efficient Nonvolatile Register Design Using MTJ Devices 150 150
Author(s): Masanori Natsui, Tomoo Yoshida, Takahiro Hanyu

Abstract:

This article proposes a circuit configuration for an area- and energy-efficient nonvolatile register using magnetic tunnel junction (MTJ) devices, suitable for persistent computation in intermittent computing environments. The proposed configuration, named the reference-load sharing scheme (RLSS), stores 1 bit of information using the resistance of a dedicated MTJ device and a …

SLiMDO: A Single-Link Multi-Domain-Output Isolated DC–DC Converter With Passive Magnetic Flux Sharing for Local Energy Distribution and Rx Behavior Sensing-Based Global Power Modulation

SLiMDO: A Single-Link Multi-Domain-Output Isolated DC–DC Converter With Passive Magnetic Flux Sharing for Local Energy Distribution and Rx Behavior Sensing-Based Global Power Modulation 150 150
Author(s): Jianqiang Jiang, Lei Zhao, Junyao Tang, Cheng Huang

Abstract:

This article introduces a small form-factor single-link multi-domain-output (SLiMDO) isolated dc–dc converter design. The proposed design provides two regulated outputs in separate domains in the receiver (Rx) side with a single micro-transformer. These isolated Rxes achieve local voltage regulation and automatic energy distribution across domains through passive magnetic flux …

FIMA: A Scalable Ferroelectric Compute-in-Memory Annealer for Accelerating Boolean Satisfiability

FIMA: A Scalable Ferroelectric Compute-in-Memory Annealer for Accelerating Boolean Satisfiability 150 150
Author(s): Mohammad Khairul Bashar, T. H. Pantha, Z. Li, M. Farasat, S. Datta, V. Narayanan, S. Dutta, N. Shukla

Abstract:

In-memory compute kernels present a promising approach for addressing data-centric workloads. However, their scalability—particularly for computationally intensive tasks solving combinatorial optimization problems such as Boolean satisfiability (SAT), which are inherently difficult to decompose—remains a significant challenge. In this work, we propose a ferroelectric nonvolatile memory (NVM)-based compute-in-memory …
