旺宏電子找到了快閃記憶體的解決辦法.


(Phys.org)—Taiwan-based Macronix has found a solution for a weakness in
flash memory fadeout. A limitation of flash memory is simply that eventually
it cannot be used; the more cells in the memory chips are erased, the less
useful to store data. The write-erase cycles degrade insulation; eventually
the cell fails. "Flash wears out after being programmed and erased about
10,000 times," said the IEEE Spectrum. Engineers at Macronix have a solution
that moves flash memory over to a new life.

They propose a "self-healing"
NAND flash memory solution that can survive over 100 million cycles. Ads by

the IEEE Spectrum, discussing flash memory's limitations and the Taiwan
company's solution. Macronix is a manufacturer in the Non-Volatile Memory
(NVM) market, with a NOR Flash, NAND Flash, and ROM products. Before their
solution announcement, though, many engineers inside and outside of Macronix
were aware of a life-giving workaround: heat. The snag is that applying heat
was not found to be practical.


As the Macronix team put it, the "long baking
time is impractical for real time operation." Although subjecting the cells
to high heat could return memory, the process was problematic; the entire
