Leti Presentation at IEDM 2013 Will Report Phase-Change Memory Developments for Microcontroller Embedded Applications
GRENOBLE, France --(Business Wire)--
A CEA-Leti and STMicroelectronics (News - Alert) paper at IEDM 2013 in December will
present an innovative back-end-of-line (BEOL), phase-change memory (PCM)
technology that is positioned to become the dominant new embedded
non-volatile memory (NVM) technology in future microcontroller
The BEOL memory solution is based on a new Ge-rich Ge2Sb2Te5
material with N- or C-dopants. It is able to optimize the SET
performance and the high temperature thermal stability of phase-change
These innovative materials have been extensively characterized through
physicochemical analysis and electrical tests and have been integrated
in state-of-the-art memory cell prototypes.
The research at Leti shows a breakthrough, fully enabling PCM technology
for microcontroller embedded applications, in which data integrity after
the peak temperature of reflow soldering must be ensured.
The co-authored paper, "Trade-off Between SET and Data Retention
Performance Thanks to Innovative Materials for Phase-Change Memory",
will be presented during Session 21 at IEDM 2013 in Washington, D.C.,
Emerging BEOL memories offer significant potential for embedded
applications because they are independent of baseline CMOS and offer
lower cost and improved performance. That makes them a promising,
potential future alternative to embedded non-volatile Flash
technologies. Issues that remain to be resolved before the technology
can be industrialized include manufacturing maturity, understanding
failure mechanisms and mitigation strategies.
Another paper written by Leti researchers also will report on innovative
memory. It deals with a more explorative emerging resistive-memories
technology that is extremely promising for future very low-power
applications. The Session 30 paper is titled: "Investigation of the
Physical Mechanisms Governing Data Retention in Down to 10nm Nano-Trench
Al2O3/CuTeGe Conductive Bridge RAM (News - Alert) (CBRAM)."
By creating innovation and transferring it to industry, Leti is the
bridge between basic research and production of micro- and
nanotechnologies that improve the lives of people around the world.
Backed by its portfolio of 2,200 patents, Leti partners with large
industrials, SMEs and startups to tailor advanced solutions that
strengthen their competitive positions. It has launched more than 50
startups. Its 8,000m² of new-generation cleanroom space feature 200mm
and 300mm wafer processing of micro and nano solutions for applications
ranging from space to smart devices.
