Some embodiments include apparatuses and methods including memory cells and a control unit to store information in a portion of the memory cells and to generate an entry associated with the information. The information is associated with a logical address recognized by a host. The entry includes an indicator indicating that the information is to be preserved for a creation of an image of information associated with logical addresses in a logical address space recognized by the host.

Logical address history management in memory device

The present disclosure includes methods, devices, and systems for error detection/correction based memory management. One embodiment includes performing a read operation with respect to a particular group of memory cells of a memory device and, if the read operation results in an uncorrectable error, determining whether to retire the particular group of memory cells in response to a status of an indicator corresponding to the particular group of memory cells, wherein the status of the indicator indicates whether the particular group of memory cells has a previous uncorrectable error associated therewith.

Error detection/correction based memory management

Systems and methods are disclosed for storing the firmware and other data of a flash memory controller, such as using a RAID configuration across multiple flash memory devices or portions of a single memory device. In various embodiments, the firmware and other data used by a controller, and error correction information, such as parity information for RAID configuration, may be stored across multiple flash memory devices, multiple planes of a multi-plane flash memory device, or across multiple blocks or pages of a single flash memory device. The controller may detect the failure of a memory device or a portion thereof, and reconstruct the firmware and/or other data from the other memory devices or portions thereof.
