SYSTEM AND METHOD FOR REPORTING AND HANDLING FLASH PROGRAMMING FAILURE IN HOST-MANAGED FLASH TRANSLATION LAYER

摘要

A computer-implemented method for facilitating handling an I/O failure is disclosed. During operation, the system receives, by a controller from a host which includes a flash-translation-layer component, a request to write a plurality of pages to a non-volatile memory device, wherein data is written sequentially in a page stripe which includes physical pages. The system generates programming status information which includes: a status which indicates a success or a failure of whether data in the current page stripe is successfully written to the non-volatile memory device; a first physical block address associated with the status; and a first number of pages which are to be padded in the current page stripe. In response to sending the programming status information to the host, the system copies valid data from the current page stripe to a new physical block address determined by the flash-translation-layer component of the host.
