Job description

Domaine : Technologies micro et nano

Contrat : Stage

Description du poste :

Cadre et contexte
The near future is Internet of Things (IoT), with the need of a data storage infrastructure allowing Big Data processing and Artificial Intelligence (AI) applications. The Memory Laboratory in CEA-LETI is developing the next generations of Non-Volatile Memories, and among them Phase-Change Memory (PCM) is the most mature one. PCM demonstrated capability of 3D stacking in Storage Class Memory applications, with an outstanding increase of data density and enabling completely new system architectures. However, in order to target microcontroller applications of the next future, where the technology node scaling will approach the nm size and the demand will dream about the Gigabyte in terms of embedded memory size, the reliability demonstration of PCM combined with innovative BackEnd selector solutions becomes mandatory.

Travail demandé :
The work will start with a bibliographic study, to analyze the main reliability challenges and programming strategies of Crossbar arrays. New phase-change material stacks combined with innovative backend selectors will be investigated. The candidate will test the electrical performance of single cell devices, and will perform statistical analysis on advanced memory arrays. Main reliability metrics will be analyzed, comparing different material stacks. The student will deal with: a) the analysis of the physics of the switching mechanisms and the impact of the temperature; b) the optimization of the programming and reading protocols in such new technology; c) the reliability of Crossbar arrays, even in high temperature environments.
