A 37.8 Mb/mm² SRAM in Intel 18A Technology Featuring a Resistive Supply-Line Write Scheme and Write-Assist With Parallel Boost Injection

A 37.8 Mb/mm² SRAM in Intel 18A Technology Featuring a Resistive Supply-Line Write Scheme and Write-Assist With Parallel Boost Injection 150 150
Author(s): Harold Pilo, Manish Arora, Chien-An Lai, Mike Lee, Zack Lo, Mayur Randeria

Abstract:

A high-density (HD), SRAM-based register file (RF) has been demonstrated in Intel 18A Technology (Wang et al., 2025 and Pilo et al., 2025) featuring RibbonFET GAA transistors and a back side power delivery network (BSDPN). The RF is optimized for HD and array efficiency and achieves a density of 37.8 Mb/mm2, the …

Comprehensive Device to System Co-Design for SOT-MRAM at the 7 nm Node

Comprehensive Device to System Co-Design for SOT-MRAM at the 7 nm Node 150 150
Author(s): Piyush Kumar, Da Eun Shim, Azad Naeemi

Abstract:

This work presents a comprehensive spin-orbit torque (SOT)-based magnetic random access memory (MRAM) design at the 7 nm technology node, spanning from device-level characteristics to system-level power performance area (PPA). At the device level, we show the tradeoffs among the write current, error rate, and time, based on mircomagnetic simulations. …
