一種易於從固態儲存裝置之故障中還原的方法,該方法由該固態儲存裝置中接收一寫入請求的該固態儲存裝置控制器實施。該方法包含:賦予一寫入請求辨識碼及一寫入大小給該固態儲存裝置中每一被寫入頁面中之一備用區;計數該寫入請求辨識碼在所有被寫入頁面中的出現次數以產生一寫入請求辨識碼數量;判斷該寫入請求辨識碼數量是否等於該寫入大小;當判斷該寫入請求辨識碼數量等於該寫入大小時,由該固態儲存裝置控制器判斷該寫入請求已完成,且該寫入請求具備在該固態儲存裝置故障後被還原的資格。 |

A method for facilitating recovery from a crash of a solid-state storage device (SSD) is adapted to be implemented by an SSD controller of the SSD that receives a write request. The method includes: assigning a write request identifier (WID) and a request size in a spare area of each written page of the SSD; counting a number of appearances of the WID in all written page(s) to result in a WID count; determining whether the WID count is equal to the request size; and determining that the write request is completed and is eligible for recovery after a crash of the SSD when it is determined that the WID count is equal to the request size. |
