In-Memory Unified TRNG and Multi-Bit PUF for Ubiquitous Hardware Security Sachin

Abstract

This work describes an SRAM architecture with in-memory generation of both dynamic and multi-bit static entropy. This inexpensively extends complete key generation capabilities to any system that includes an SRAM, and hence ubiquitously down to tightly constrained and very low cost. The array embeds a true random number generator (TRNG) and a physically unclonable function (PUF), while using a commercial bitcell and periphery all-digital pitch-matched augmentation to retain the simplicity of mem
