Abstract: Methods, systems, and devices for memory block utilization in memory systems are described. A system configured to allow a memory device to group or segment a memory block into two or more sub-memory blocks, which can be independently programmed is described herein. For example, a host system may determine a configuration of a memory array, and communicate the configuration information to the memory system, and transmit a command for an operation to the memory system. In some examples, the memory system may utilize the memory array configuration information and determine to segment the blocks of memory cells into sub-blocks. By segmenting the memory block into sub-blocks, the memory device may maintain its memory block density while supporting efficient programming of blocks of the memory array.

Abstract: Apparatuses, media, and methods associated with providing guidance while performing tasks are described. Guidance can be provided in the form of directions for reaching a destination. For example, the guidance can include determining a destination and/or providing directions to reach the destination in the least amount of time. The guidance can include directions in the form of audible turn by turn instructions, a route shown on a map, and/or indications by streetlights or street signs (e.g., the route to the destination is indicated by flashing streetlights or words shown on street signs), among other types of guidance. Guidance can be provided in the form of instructions for performing a task. For example, the guidance can include instructions for treating a medical condition of an individual in an ambulance.

Abstract: Methods, systems, and devices for assigning blocks of memory systems are described. Some memory systems may be configured to initiate an operation to characterize a plurality of blocks of a memory system; identify a first quantity of complete blocks of the plurality of blocks and a second quantity of reduced blocks of the plurality of blocks based at least in part on initiating the operation; determine, for a block of the second quantity of reduced blocks, whether a quantity of planes available for use to store the information in the block satisfies a threshold; and assign the block as a special function block configured to store data associated with a function of the memory system based at least in part on determining that the quantity of planes available for use to store the information in the block of the second quantity of reduced blocks satisfies the threshold.

Abstract: A memory sub-system to initiate an erase operation to erase a first set of memory cells of a first memory block and a second set of memory cells of a second memory block of a memory device. One or more erase pulses of the erase operation are caused to be applied to the first set of memory cells of the first memory block and the second set of memory cells of the second memory block concurrently. A first erase verify sub-operation of the erase operation is caused to be performed to verify the first memory block is erased and a second erase verify sub-operation of the erase operation is caused to be performed to verify the second memory block is erased.

Abstract: Methods, systems, and devices for critical data management within a memory system are described. A memory system may avoid writing critical data to weak word lines. For example, as part of a media management operation or a host write operation (among other examples), the memory system may determine which data is critical data and may determine which word lines are weak word lines, which may refer to word lines having bit error rates that satisfy a threshold. The memory system may refrain from writing critical data to memory cells coupled with weak word lines, and may instead write non-critical or dummy data to the weak word lines. The memory system may reserve the writing of critical data to memory cells coupled with non-weak word lines, which may refer to word lines having bit error rates that fail to satisfy the threshold.

Abstract: Methods, systems, and devices for suspension during a multi-plane write procedure are described. A memory system may perform a multi-plane write procedure by writing to a set of planes in parallel. Upon detecting a defective plane in the set of planes, the memory system may suspend writing to the defective plane until writing to the other planes in the set of planes is finished. The memory system may then resume writing to the defective plane.
