Abstract
A method for reprogramming data, performed by a processing unit, is disclosed to include at least the following steps. After a page of data has failed to be programmed into a first block of a storage unit, it is determined whether the failed page is an upper page or a first lower page. When the failed page is an upper page, a host page number associated with a second lower page of a wordline including at least the failed page is obtained, a second block is selected, and an access interface is directed to reprogram data from the second lower page to the upper page into the second block.
Claims16
A method for reprogramming data, performed by a processing unit, comprising:
- after inspecting that a page of data has failed to be programmed into a first block of a storage unit, determining whether the failed page is an upper page or a first lower page;
- when the failed page is the upper page, obtaining a host page number associated with a second lower page of a wordline comprising the failed page;
- when the failed page is the upper page, selecting a second block;
- and
- when the failed page is the upper page, directing an access interface to reprogram data from the second lower page to the upper page into the second block.
An apparatus for reprogramming data, comprising:
- an access interface, coupled to a storage unit;
- and
- a processing unit, coupled to the access interface, after inspecting that a page of data has failed to be programmed into a first block of a storage unit, determining whether the failed page is an upper page or a first lower page;
- when the failed page is the upper page, obtaining a host page number associated with a second lower page of a wordline comprising the failed page, selecting a second block and directing an access interface to reprogram data from the second lower page to the upper page into the second block.
