Abstract
Technology for an apparatus is described. The apparatus can include a first non-volatile memory, a second non-volatile memory to have a write access time faster than the first non-volatile memory, and a memory controller. The memory controller can be configured to detect corrupted data in a selected data region in the first non-volatile memory. The selected data region can be associated with an increased risk of data corruption after data is written from the second non-volatile memory to the first non-volatile memory. Uncorrupted data in the second non-volatile memory that corresponds to the corrupted data in the first non-volatile memory can be identified. Data recovery in the first non-volatile memory can be performed by replacing the corrupted data in the first non-volatile memory with uncorrupted data from the second non-volatile memory.
