The storage class memory device may execute an access command for a first page in the storage class memory device. The storage class memory device may also determine whether a failure occurred while executing the access command. The storage class memory device may create an entry in a journal for the storage class memory device if a failure occurred while executing the access command. The storage class memory device may refrain from creating the entry if a failure does not occur while executing the access command.

Abstract: Systems and methods for offloading data transformation from a host to a hybrid solid state drive (HSSD) are described. In one such method, the HSSD receives initial data from the host and stores the data at a first non-volatile memory (NVM). The HSSD receives a transformation command from the host to offload data transformation. The HSSD copies the data from the first NVM to a second NVM that is configured to provide a finer granularity of data access than that of the first NVM. Then the HSSD transforms the data at the second NVM utilizing the configured processing circuit. The HSSD may store the result in the first NVM and/or second NVM, and send it to the host.

Abstract: A non-volatile storage system is configured to reclaim bad blocks. One embodiment includes determining that a block of non-volatile memory cells is a bad block, leaving the block idle for a period of time to allow for self-curing of the block, verifying success of the self-curing, refreshing the block, verifying that the refresh was successful and subsequently using the block to store host data.

Abstract: NAND cell error remediation technologies are disclosed. The remediation technologies are applicable to 3D NAND. In one example, a storage device may include a processor and a memory device comprising NAND flash memory.
