Abstract
A data storage device is disclosed comprising a volatile memory, a primary and a secondary non-volatile memory (NVM), and control circuitry coupled to the volatile memory and the primary and secondary NVM and configured to write first data to the volatile memory, write the first data from the volatile memory to the secondary NVM before writing the first data to the primary NVM, attempt to write the first data to the primary NVM, wherein, during the attempt to write the first data to the primary NVM, after a portion of the first data has been successfully written to the primary NVM, a corresponding portion of the first data is released from the secondary NVM.
