Abstract
Method and apparatus for managing data in a memory. In accordance with some embodiments, input write data having a selected logical address are stored in a rewriteable non-volatile (NV) buffer. A copy of the input write data is transferred to an NV main memory using a sloppy write process. A verify operation is subsequently performed to verify successful transfer of the copy of the input write data to the NV main memory using a hash value generated responsive to the input write data in the NV buffer.
