The Highlight Paper selected for 2017 IEDM focuses on realizing a 128Gb MLC (or 192Gb TLC) 3D NAND Flash using the SGVC architecture with only 16 layers. Such memory density is comparable to 48-layer 3D NAND using a popular gate-all-around (GAA) structure. SGVC has the important advantage of much smaller cell size and pitch scaling capability which allows very high-density memory with much fewer stacking layers. The 3D SGVC NAND makes use of arrays of vertically arranged single-gate flat-cell thin film transistors with an ultra-thin body, which aren't as sensitive to variation of critical dimensions (CD) as GAA devices, and is very suitable for read-intensive memory applications.
The other three Macronix papers chosen for 2017 IEDM include one that proposes a model to understand the operational physics of junction-free structure and Wordline (WL) interference effects in a 3D NAND. Another paper deals with ovonic threshold switching (OTS) chalcogenide material system (TeAsGeSi) that incorporates Se and an extra dopant. The resulting new selector demonstrated excellent endurance and OTS characteristics suitable for 3D stackable cross-point high-density non-volatile memory. The third one discusses retention behavior of high resistance state (HRS) of ReRAMs (resistive random access memories).
Macronix has published more than 60 papers at IEDM since 2003. In recent years, Macronix was usually among the top of Taiwan-based institutions in number of papers presented at IEDM. Every two to three years, Macronix had papers chosen for Highlight Papers. Up to now, Macronix has authored 6 IEDM Highlight Papers. Especially, in 2012 Macronix presented two Highlight Papers. This year, there are 16 Highlight Papers for IEDM, Macronix's paper is the only one from Taiwan-based companies and academic institutes. This demonstrated Macronix's leading competitiveness in global advanced memory technologies.
There are about 600 papers submitted to IEDM each year on average with about 200 selected for 10 categories through strict review for publication at the meeting. In the Memory Technology category, only 25 papers will be presented at 2017 IEDM and Macronix's number of selected papers is the highest in the category. This year, 17 selected papers on first author base are from Taiwan with 11 papers from enterprises (including Macronix's 4 papers) and 6 papers from a research institute and universities.
