A 48-minute conference talk from the Storage Developer Conference 2022 explores the impact and legacy of persistent memory technologies, particularly focusing on Intel's Optane products and their influence on computing architecture. Dive into the evolution of emerging memory technologies, examining their role in replacing traditional on-chip memories and the developments fostered through SNIA and other organizations. Understand the new Near/Far Memory paradigms that led to interface protocols like CXL and OMI, while exploring how chiplets are reshaping persistent processor caches. Learn about the challenges faced by Intel's Optane, including cost considerations, scaling limitations of embedded NOR and SRAM, and the implications for future processor designs. Gain insights into FRAM technology, memory expansion approaches, and security concerns related to persistent memory. Industry experts Jim Handy from Objective Analysis and Thomas Coughlin from Coughlin Associates present comprehensive analysis of emerging memories entering their next phase and the potential impact of chiplet architecture on memory technology development.
