Core Concepts
ReRAM crossbars evaluation platform development for automated reliability assessments.
Abstract
The article introduces a fully automated platform for evaluating ReRAM crossbars.
It discusses the importance of understanding the stochastic behavior of ReRAM technologies.
The NeuroBreakoutBoard (NBB) is presented as an instrumentation platform for characterizing Non-Volatile Memories (NVMs).
A control board is developed to perform reliability assessments of 1T1R ReRAM crossbars.
The study focuses on analyzing Cycle-to-Cycle (C2C) variation and read disturb TiN/Ti/HfO2/TiN cells.
The paper outlines the structure, components, and validation of the proposed controller board and interface.
Results from a case study on C2C variation, read disturb, and endurance metrics are presented.
Findings suggest reading in reset direction achieves better results for read disturb in TiN/Ti/HfO2/TiN cells.
Stats
Resistive Random Access Memory (ReRAM) is a promising candidate for Computing-in-Memory (CIM) architectures.
C2C variation is associated with stability and reliability of ReRAM devices over repeated cycles of use.
