Research and Markets: Emerging Non-Volatile Memories Patent Landscape
DUBLIN --(Business Wire)--
Research and Markets (http://www.researchandmarkets.com/research/x94g4k/emerging)
has announced the addition of the "Emerging
Non-Volatile Memories Patent Landscape" report to their
The integration limit of flash memories is approaching, and emerging
Non-Volatile Memories (eNVM) to replace conventional Flash Memories have
been proposed. Ferroelectric RAMs (FeRAMs), Magnetoresistive RAMs
(MRAMs), Resistive-change RAMs (ReRAMs) or Phase-Change Random-Access
Memories (PCRAMs) are promising to change the memory landscape. The
field of eNVM has shown an intensive patenting activity since early
1990s, with a substantial increase during the past decade.
Currently, there are more than 8,600 relevant patent families filed all
over the world. Patent families were filed by more than 800 patent
applcants mainly located in USA, Japan, Taiwan and China. From a
quantitative point of view, the most active companies are SK Hynix,
Samsung, Toshiba, Micron Technology and IBM (News - Alert). In addition, startup firms
do not file many patents and their main strategy is to license or sell
their intellectual property.
The patents related to MRAM technology account for more than 40% of
filings. The main patent applicants are Toshiba, Samsung (News - Alert) and Renesas
Electronics which represent together almost 30% of the patents. The MRAM
technology was growing between 2003-2007 with more than 50% of patents
published during these years. Currently, the number of patents filed has
remained stable, with about 200 patents filed per year.
About 30% of patent families are related to PCRAM technology. They were
mainly filed by SK Hynix and Samsung, they represent almost 40% of
published patents. The PCRAM technology was increasing between 2002 and
2009, with more than 450 patent families published in 2009. Publication
patents is decreasing these last 4 years, however more than 200 patents
are still published every year. Patent filings will continue on PCRAM
technology to further improve memory applications.
The patents dedicated to FeRAM technology represent 20% of filings. They
were mainly filed by SK Hynix, Samsung and Seiko Epson which represent
almost 50% of published patents. FeRAM is a mature technology, and FeRAM
is not an active patent field yet.
Patents related to ReRAM technology account for almost 10% of new patent
filings. ReRAM is the newest patented technology and the number of
patent publications will continue to increase in the coming years. With
over 100 patent families already filed, Samsung will play a significant
role in this emerging technology development.
