    Abstract: Method and apparatus for managing a memory, such as but not limited to a flash memory. In accordance with some embodiments, initial state information is stored which identifies an actual state of a garbage collection unit (GCU) of a memory during a normal operational mode. During a restoration mode after a memory power cycle event, a virtualized state of the GCU is determined responsive to the initial state information and to data read from the GCU. The memory is transitioned from the restoration mode to the normal operational mode once the virtualized state for the GCU is determined.

    Abstract: Method and apparatus for managing data in a memory, such as a flash memory. In accordance with some embodiments, the apparatus has a solid-state non-volatile memory and a processing circuit configured to write data to a selected location of the memory. The data are arranged in the form of multi-bit code words each comprising a user data payload and associated parity data configured to correct one or more bit errors in the user data payload. The processing circuit adjusts at least a selected one of a size of the code words, a size of the user data payloads or a size of the parity data responsive to at least a selected one of an accumulated count of access operations upon the selected location or an error rate associated with the selected location.

    Abstract: Method and apparatus for managing data in a memory, such as a flash memory. In accordance with some embodiments, a memory module has a plurality of solid-state non-volatile memory cells. A controller communicates a first command having address information and a first operation code. The first operation code identifies a first action to be taken by the memory module in relation to the address information. The controller subsequently communicates a second command having a second operation code without corresponding address information. The memory module takes a second action identified by the second command using the address information from the first command.
