Abstract: A first type of command is suspended, by a controller of a non-volatile memory device, in response to determining that a second type of command is waiting for execution. The first type of command is split into a plurality of chunks based on a computed criteria. A second type of command is executed in between execution of at least two chunks of the first type of command.

Abstract: A solid state drive (SSD) includes a nonvolatile memory array and a cache memory. The nonvolatile memory array has an encrypted integrated memory buffer (IMB) space. The cache memory has a decrypted copy of the IMB and an encrypted backup copy of the IMB. In power loss recovery (PLR) after a power loss imminent (PLI) event, the SSD can determine whether to recover the unencrypted copy of the IMB or the backup encrypted copy. The backup encrypted copy can reduce the risk of loss of data in the IMB in the event that multiple PLI events occur and a corrupted copy of the IMB is used to overwrite the IMB in the nonvolatile memory during a previous PLR.
