Abstract
A storage system and method for marginal write-abort detection using a memory parameter change is provided. In one embodiment, a method for detecting a write abort is provided that is performed in a storage system having a memory. The method comprises reading a lower page in memory; determining if any data is written in the lower page; and in response to determining that no data is written in the lower page: increasing source voltage for memory cells in the lower page; re-reading the lower page; determining if a read failure exists in the re-read lower page; and in response to determining that a read failure exists in the re-read lower page, detecting a write abort. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.
