A method may comprise issuing a first cache program operation from a storage controller to a non-volatile storage device to write data to a first regular block, writing the data to the first regular block and a copy of the data to a backup block, determining that a program error has occurred while writing the data to the first regular block, asserting the program error to the storage controller, retrieving a mapping between the first regular block and the backup block, issuing a read operation to read the copy of the data from the backup block, reading the copy of the data from the backup block and issuing a second cache program operation to write the data to a second regular block and marking the first regular block as defective."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cache program with backup blocks","description":"Systems, apparatus and methods are provided for performing cache program operations in a non-volatile storage system.
