Comparative analysis of sense amplifier circuits for hybrid CMOS-MTJ CIM architecture

Comparative analysis of sense amplifier circuits for hybrid CMOS-MTJ CIM architecture 150 150
Author(s): Yashvardhan Singh, Siddharth Penumatsa, Prashanth Barla

Abstract:

Spin-transfer torque magnetic tunnel junction (STT-MTJ) is widely recognized as a promising device for computation-in-memory (CIM) architecture due to its advantages such as simple non-volatile structure, CMOS compatibility and scalability. In spite of the advantages, achieving a reliable and efficient sensing of STT-MTJ remains a design challenge. This work presents …

A 256-Element Slepian Beamforming Accelerator with Analog Compute-In-Memory Multiplication and Accumulation

A 256-Element Slepian Beamforming Accelerator with Analog Compute-In-Memory Multiplication and Accumulation 150 150
Author(s): Wei-Chun Wang, Shida Zhang, Coleman DeLude, Laith Shamieh, Nael Mizanur Rahman, Isha Chakraborty, Justin Romberg, Saibal Mukhopadhyay

Abstract:

An analog compute-in-memory Slepian beamforming accelerator is introduced for large-scale MIMO. The design performs complex-valued vector–matrix multiplication in the analog domain to project 256 I/Q inputs into a low-dimensional Slepian subspace and uses a digital backend with 4-tap FIR filters to generate one output beam. A test chip fabricated …

Benchmarking of Emerging Material-Based TCAMs

Benchmarking of Emerging Material-Based TCAMs 150 150
Author(s): Ashwin Tunga, Junzhe Kang, Zijing Zhao, Ankit Shukla, Wenjuan Zhu, Shaloo Rakheja

Abstract:

This work presents a comprehensive benchmarking of ternary content-addressable memory (TCAM) implementations using timing-accurate SPICE simulations, systematically comparing conventional CMOS designs with emerging device technologies, including magnetic tunnel junctions (MTJs), ferroelectric tunnel junctions (FTJs), ferroelectric field-effect transistors (FeFETs), and two-dimensional reconfigurable field-effect transistors (2D RFETs). Key performance metrics, including search …
