    Abstract: Apparatus and methods are disclosed, including determining whether firmware has been successfully loaded and whether the firmware version is valid and operable, and if the firmware has not been successfully loaded or the firmware is not valid and operable, tracking a number of unsuccessful attempts to load the firmware or an elapsed time for unsuccessful attempts to load the firmware, and entering a memory device into a reduced-power state if either the number of unsuccessful attempts or the elapsed time has reached a programmable threshold.

    Abstract: Devices and techniques for logical-to-physical (L2P) map (e.g., table) synchronization in a managed memory device are described herein. For example, plaintext portion of an L2P map may he updated in a managed memory device. In response to updating the plaintext portion of the L2P map, the updated portion can be obfuscated to create an obfuscated version of the updated portion of the L2P map. Both the updated portion and the obfuscated version of the updated portion can be saved in storage of the memory device. When a request from a host for the updated portion of the L2P map is received, the memory device can provide the obfuscated version of the portion from the storage.

    Abstract: Apparatus and methods are disclosed, including using a memory controller to partition a memory array into a first portion and a second portion, the first portion and second portion having non-overlapping logical block addressing (LBA) ranges. The memory controller assigns a first granularity of a first logical-to-physical (L2P) mapping table entry for the first portion of the memory array designated for a first usage, and a second granularity of a second L2P mapping table entry for the second portion of the memory array designated for a second usage, where the second granularity is not equal to the first granularity. The memory controller stores the first granularity and the second granularity in the memory array, and stores at least a portion of the first L2P mapping table entry and the second L2P mapping table entry in an L2P cache of the memory controller.
