heating can cause worn-out NAND flash cells to become reusable

"heating can cause worn-out NAND flash cells to become reusable
and greatly prolong the lifetime of flash memory cells"


nand flash的cell居然可以經由加熱來提高 life time ,還可以起死回生勒


rather than evenly distributing writes and erases over a time period,
write and erase operations are concentrated on a small portion of
flash memory cells, so that these cells can be worn-out and healed
by heating first. In this way, we can disperse healing to avoid the
problem of concentrated power usage caused by heating


以前 Wear-leveling 重點都在 "分散"  write 和 erase
但因為 heating (加熱) 需要秏額外的 power ,所以此篇 將 write 和 erase 給 "集中起來"
~~ 一起加熱
