The Unexpected<br />
SNU research team led by<br />
Professor Park Byung-gook presents something innovative<br />
Technologies are universal, both<br />
by nature and by name, mostly in<br />
abbreviated form. Throw out<br />
"cell phone", "computer" or "telev<strong>is</strong>ion"<br />
anywhere and chances are you will not be<br />
alienated. But Cone SONOS flash memory?<br />
For th<strong>is</strong> rare technology, we are at<br />
once baffled by its idiosyncratic term.<br />
<strong>Korea</strong>n research team from Seoul<br />
National University (SNU) invented<br />
'NOR Flash Memory' that processes data<br />
faster by ten times for the first in the world.<br />
The research team led by Professor Park<br />
Byung-gook made it all the more possible<br />
for next-generation digital devices <strong>to</strong> be<br />
faster because NOR flash memory can be<br />
housed in<strong>to</strong> cell phones, smart phones,<br />
TVs, and other gadgets.<br />
Professor Park and h<strong>is</strong> team invented a<br />
cone-shaped NOR flash memory instead<br />
of the original, flat shaped, hence, breaking<br />
the norm. They announced on January 20<br />
that they succeeded in developing another<br />
flash memory that has relevant speed and<br />
data s<strong>to</strong>rage that of NAND.<br />
NOR has been commonly used in cell<br />
phones for they are fast in processing<br />
memory s<strong>to</strong>rage. NOR and NAND <strong>is</strong> divided<br />
by their circuit type and shape; unlike<br />
DRAM, they are able <strong>to</strong> continue<br />
s<strong>to</strong>ring information even after the power <strong>is</strong><br />
turned off. Nonetheless, the former flatshaped<br />
NOR was often criticized for its inefficiency<br />
because of low accumulation<br />
Cone SONOS flash memory<br />
and low capacity.<br />
SNU research team significantly improved<br />
information record and deleting<br />
rate by extending the memory channel <strong>to</strong> a<br />
cone-shaped and stretching the travel d<strong>is</strong>tance<br />
of electrons. And by cutting the<br />
NOR's area by one fifth, they achieved in<br />
boosting its accumulation rate <strong>to</strong> the level<br />
and speed of NAND. All in all, SNU research<br />
team <strong>is</strong> applauded for the possibility<br />
of entering the consumer's market of<br />
selling NOR flash memory the size of<br />
32GB.<br />
"Th<strong>is</strong> current technology based off of<br />
changing the entire shape of NOR has allowed<br />
procuring the most innovative technology,"<br />
said Professor Park.<br />
Such research result has already been<br />
uploaded on the recent IEEE Electron<br />
Device Letters and <strong>is</strong> in the process of obtaining<br />
a patent both domestic and in the<br />
U.S.<br />
