Advances and Trends in Low-Power Logic-Compatible Phase Change Memory (PCM): A Comprehensive Survey Saranyanandhini D, Shanmugasundaram N, Mohan Kumar M, Nandhini M 2026 2nd International Conference on Intelligent Systems for Communication Iot and Security Iciscois 2026, 2026 Phase Change Memory (PCM) is a non-volatile technology which has received significant interest as a next-generation compute in-memory technology and artificial intelligence, as well as a high performance and energy efficient embedded system. This paper contains an in-depth experimental study of lowpower, logic compatible 40 nm PCM cells, principally regarding their reliability, reliability, and compatibility with neuromorphic and artificial intelligence devices. The wide characterization of the devices included endurance cycling, resistance drift experiments, high temperature data retention tests, and variability tests. At 120° C, retention studies indicate that with a heat of more than 120° C a memory life of more than ten years is observed and endurance tests indicates good performance up to 200,000 program/erase cycles with no memory window erosion. The measurements of drift in high resistance and low resistance stages reflect the resistance development that is well controlled and statistical measures confirm narrow distributions that are vital to stable operation and multi-level programming. The potential of PCM arrays is also validated by analysis in binary neural network models, wherein the robustness of the performance of the simulated inference distributions is obtained with simulated noise and unpredictability in the devices. On the whole, the results make low power PCM one of the leaders in embedded and artificial intelligence computing systems that offer scalable integration of the system, a high endurance level, precise programmability, and long term data retention.
Comparative Analysis on Cold CMOS in Advanced FinFET Technology at 300 K and 77 K Mohanapriya K, Shanmugapriya A, Mohankumar M, Saranyanandhini D Proceedings of the 4th IEEE International Conference on Interdisciplinary Approaches in Technology and Management for Social Innovation Iatmsi 2026, 2026 This work investigates the behavior of CMOS circuits operating at low temperature using advanced FinFET technology. A comparative study is carried out between room temperature operation at 300 K and cryogenic operation at 77 K to understand the impact of temperature scaling on device and circuit performance. As CMOS devices continue to scale, issues such as leakage power, thermal noise, and performance variability have become critical challenges, especially for high-speed and low-power applications. Operating transistors at cryogenic temperatures helps reduce these effects by improving carrier mobility and suppressing leakage mechanisms. In this study, physics-based simulations are performed to extract important device parameters including drive current, leakage current, threshold voltage, subthreshold swing, and transconductance under different bias conditions. In addition, interconnect effects are considered to evaluate changes in wire resistance and signal delay at low temperature. Circuit-level analysis using a FinFET-based CMOS inverter is used to examine delay and power consumption. The results show noticeable improvement in switching speed and a significant reduction in leakage and power dissipation at 77 K. Overall, the combined device, interconnect, and circuitlevel analysis confirms that cryogenic FinFET CMOS operation is a promising approach for future lowpower and high-performance systems, particularly in applications such as quantum control electronics and cryogenic computing platforms.

Low Frequency Single Cycle Multi-Hop NoCs for High Performance and Energy Efficiency Mohammed Adhil H, Mohankumar M 2025 IEEE International Conference on Modern Electronics Devices and Intelligent Communication Systems Medcom 2025, 2025 The rapid growth in the size of modern multicore processors in terms of the number of cores has increased the need to have effective on-chip communication systems. The conventional Network-on-Chip (NoC) architecture has serious scalability challenges because of the enhanced latency and energy dissipation incurred by the quantity of hops between communication cores. Current methods usually entail tradeoffs, to make SMART NoCs and traditional Dynamic Voltage and Frequency Scaling (DVFS) methods tend to make higher energy efficiency of a system, or express links and high-radix routers to make less energy consumption more energy-consuming. This paper presents a new low-frequency single-cycle multi-hop (LFSCH) NoC architecture that will be used to design the architecture focused on improving the performance and energy efficiency. The most important innovation that allows operating DVFS efficiently and at the same time ensures single-cycle multi-hop traversal is the separation of router and link frequencies. The suggested design is simulated and simulated under varying frequency combinations and workloads with the help of Gem5 simulation framework. Experimentation suggests that the LFSCH NoC provides between 28% and 17% greater energy efficiency and 17% lower latency than other NoC architectures and would be sensible option in scalable and energy efficient multi-cores.

Efficient AI Accelerator based on Systolic Array Architecture with Approximate Computing Techniques Gayathri Devi B, RamKumar S, Mohan Kumar M Proceedings of 6th International Conference on Iot Based Control Networks and Intelligent Systems Icicnis 2025, 2025 This paper introduces an optimized AI accelerator that combines a systolic array architecture with approximate computing to achieve high performance and low power consumption. The architecture targets energy efficiency and hardware optimization by integrating controlled approximations into the arithmetic operations of each Processing Element (PE). In this design, the multiplier unit incorporates approximate compressors and adders, while a Constant-OR Adder (COA) is implemented in the least significant bit (LSB) region of the adder to minimize logic depth and switching activity. These enhancements significantly reduce the overall critical path delay, silicon area, and power usage while maintaining reliable computational accuracy for AI and deep learning tasks. The systolic array framework ensures synchronized data flow through multiple PE arrays and columns, supporting parallel and pipelined matrix operations. Additionally, the use of a 16-register data management scheme improves data reuse and accelerates processing throughput. Experimental and synthesis results reveal that the proposed approximate systolic array outperforms conventional exact designs, achieving substantial reductions in delay, area, and energy consumption. The outcomes confirm that small arithmetic approximations can yield major efficiency gains without degrading output quality. Consequently, this design represents a promising approach for developing compact, high-speed, and power-aware AI accelerators suitable for edge and embedded intelligent systems.

Optimized Design of Clock-Gated D Flip-Flop using Transmission Gate Jeevitha R, Mohankumar M, Gayathri Devi B, Mohammed Adhil H Proceedings of 3rd International Conference on Augmented Intelligence and Sustainable Systems Icaiss 2025, 2025 Modern digital applications will call for very fast and optimum devices because they are associated with minimal delay and power. Through a transmission gate, the proposed design employs a low-power clock pulsed data flip-flop (D flip-flop). This study proposes to use the clock gating technique to design a low-power pulsed D flip-flop. By reducing transistor switching, the gated clock reduces the circuit's dynamic power usage. One of the methods of applying clock gating is to disrupt the circuit’s clock input using an OR gate in relation to the signal Enable. This method makes the clock idle to reduce power consumption when the output is at a particular steady state. This research therefore puts forth a concept of a clock-pulsed low power D Flip Flop (DFF) structural design based on the use of transmission gates to enhance the power efficiency of digital circuits. The proposed DFF is intended for constructing a 4-bit serial in parallel-out shift register to show the efficient performance of low power applications. The cadence tool with 90nm technology is also used to simulate all the designs and what is observed is that the tool provides better power, number of transistors, and delay efficiency.
