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.
沒什麽 就是CELL 會慢慢恢復寫/讀 |

" Although subjecting the cells to high heat could return memory, the process was problematic; the entire memory chip would need heating for hours at around 250 °C.
For their upcoming IEEE presentation, they said they propose and demonstrate a novel self-healing flash, where a high temperature (>800°C), and short time annealing are generated by a built-in heater. 這.... |

我可沒那麽大的本事說是唬爛的 只是要在短時間内把 CELL 溫度提升到250度讓 CELL 恢復 如果要在比如手機裏面使用 散熱要做好啊 |

短時間是八百度不是250度喔. (250度要烤它幾個小時才有用) 照這樣看一般家用產品的FLASH沒辦法隨機自我恢復. (瞬間攝氏八百度耶!Flash memory恢復了其他組件也全掛了) 所以說未來"好便宜的SSD"可能是回收品. 再處理,再生產,出貨再出貨銷售? |

根據湯米的節錄, 或許是個機會
 如果可以用更多的時間換取更低的溫度, 這將會是硬碟廠的噩夢

量子狀態下溫度的意涵跟日常生活的感受其實差很多
這個800度指的是微觀下瞬間那群電子具備的態改變頻率的能力 其實並不會難以想像，例如尖端放電或者日光燈激發，溫度都遠比800度高的多但 假如800度指的是巨觀的環境環境，就根本難以達成 其實高溫可以恢復Flash的退化，幾年前就已經知道了 現在是看說是不是也有辦法把這個機制用電路做進去裡面 |

目前SSD的唯二缺點：價格昂貴和讀寫次數限制，
價格問題已經越來越小了，如果讀寫次數限制能改善， 傳統硬碟廠應該都會很擔心。
