Abstract: Methods, systems, and apparatuses include receiving a write command including user data. The write command is directed to a portion of memory including a first and second block and a first and second user data portion are directed to the first and second block. Temporary parity data is generated using the first and second user data portions. The temporary parity data and the first and second user data portions are stored in a buffer. Portions of the first and second block are programmed with two programming passes. The first and second user data portions in the buffer are invalidated in response to a completion of the second programming pass of the portions of the first and second blocks. The temporary parity data is maintained in the buffer until a second programming pass of the first and second block.

Abstract: Methods, systems, and apparatuses include receiving a write command including user data. The write command is directed to a portion of memory including a first block and a second block. A buffer is allocated for executing the write command to the first block. The buffer includes multiple buffer decks and the buffer holds the user data written to the first block. User data is programmed into the first block to a threshold percentage. The threshold percentage is less than one hundred percent of the first block. A buffer deck is invalidated in response to programming the first block to the threshold percentage. The buffer deck is reallocated to the second block for programming the user data into the second block. The buffer deck holds user data written to the second block.

Abstract: Methods, systems, and apparatuses include retrieving a defectivity footprint of a portion of memory, the portion of memory composed of multiple blocks. A deck programming order is determined, based on the defectivity footprint, for a current block of the multiple blocks. The current block is composed of multiple decks. The deck programming order is an order in which the multiple decks are programmed. The multiple decks programmed according to the determined deck programming order.

Abstract: Methods, systems, and devices for plane balancing in a memory system are described. A memory system may select a memory die for writing a set of data. The memory die may include a plurality of planes each of which may include a respective plurality of blocks of memory cells. Based on selecting the memory die, the memory system may determine a first plane of the plurality of planes that has a first quantity of blocks with an availability status and a second plane of the plurality of planes that has a second quantity of blocks with the availability status. The memory system may write the set of data to the plurality of planes, excluding at least the first plane, based at least in part on the first quantity of blocks and the second quantity of blocks.
