Memory controllers can include a switch and non-volatile memory control circuitry including channel control circuits coupled to the switch. The channel control circuits can coupled to logical units including blocks. Volatile memory and memory management circuitry including local memory can be coupled to the switch. The memory management circuitry can be configured to store health and status information for each of the blocks in a block table in the volatile memory, store a candidate block table that identifies a candidate block for a particular operation based on criteria in the local memory, update the health and status information for a particular block in the block table, compare the updated health and status information for the particular block with the candidate block according to the criteria, and update the candidate block table to identify the particular block in response to the comparison indicating that the particular block better satisfies the criteria. |
