Abstract: Methods, systems, and devices for a deck-based erase function are described. A memory system may perform alternating erase operations and write operations on a virtual block configured with blocks constructed from half good blocks (HGBs). For example, the memory system may erase and subsequently write data to a first subset of HGBs associated with one or more memory dies of the memory system, before erasing and subsequently writing data to a second subset of HGBs associated with the one or more memory dies. In some cases, the memory system may determine the first subset of HGBs has been filled by the write operations, prior to erasing the second subset of HGBs. In other cases, the memory system may identify an idle time during writing to the first subset of HGBs, and begin erasing the second subset of HGBs during the idle time.

Abstract: Methods, systems, and devices for block replacement using combined blocks are described. A memory system may receive a command to perform an access operation on a block of the memory system. The memory system may determine whether a block pool includes a second block configured to replace the block based on a failure to perform the access operation. The memory system may generate a combined block for replacing the block based on determining an absence of the second block in the block pool. The combined block may be generated by combining two half good blocks (HGBs) in a same plane of the memory system as the block. In some cases, a second block pool may be generated and the combined block may be stored to the second block pool. The memory system may select the combined block from the second block pool and replace the block with the combined block.
