Exploring liquid-based memories for ultrahigh-density storage applications

The potential of colloidal and electrolithic memories for nearline storage


From 2030 onwards, new types of storage technologies are expected to enter the memory roadmap, complementing 3D-NAND-Flash, hard disk drives, and tapes in the latency/productivity space.

In this article, Maarten Rosmeulen, program director of storage memory at imec, introduces two new liquid-based storage concepts: colloidal and electrolithic memory.

He explains the basic operating principles, shows the first experimental results, and highlights their potential for future nearline storage applications.

These liquid memories were recently presented in an invited paper at the 2022 International Memory Workshop (IMW).
