Methods, systems, and devices for a dynamic error control configuration for memory systems are described. The memory system may receive a read command and retrieve a set of data from a location of the memory system based on the read command. The memory system may perform a first type of error control operation on the set of data to determine whether the set of data includes one or more errors. If the set of data includes the one or more errors, the memory system may retrieve a second set of data from the location of the memory system and determine whether a syndrome weight satisfies a threshold. The memory system may perform a second type of error control operation on the second set of data based on determining that the syndrome weight satisfies the threshold.

Methods, systems, and devices for techniques for managing temporarily retired blocks of a memory system are described. In some examples, aspects of a memory system or memory device may be configured to determine an error for a block of memory cells. For example, a controller may determine an existence of the error and may temporarily retire the block. A media management operation may be performed on the temporarily retired block and, depending on one or more characteristics of the error, the temporarily retired block may be enabled or retired.

Methods, systems, and devices for techniques for retiring blocks of a memory system are described. In some examples, aspects of a memory system or memory device may be configured to determine an error for a block of memory cells. Upon determining the occurrence of the error, the memory system may identify one or more operating conditions associated with the block. For example, the memory system may determine a temperature of the block, a cycle count of the block, a quantity of times the block has experienced an error, a bit error rate of the block, and/or a quantity of available blocks in the associated system. Depending on whether a criteria associated with a respective operating condition is satisfied, the block may be enabled or retired.

A memory device comprises a memory control unit including a processor configured to control operation of the memory array according to a first memory management protocol for memory access operations, the first memory management protocol including boundary conditions for multiple operating conditions comprising program/erase (P/E) cycles, error management operations, drive writes per day (DWPD), and power consumption; monitor operating conditions of the memory array for the P/E cycles, error management operations, DWPD, and power consumption; determine when a boundary condition for one of the multiple operating conditions is met; and in response to determining that a first boundary condition for a first monitored operating condition is met, change one or more operating conditions of the first memory management protocol to establish a second memory management protocol for the memory access operations, the second memory management protocol including a change boundary condition of a second monitored operating condition.

Methods, systems, and devices for maintenance command interfaces for a memory system are described. A host system and a memory system may be configured according to a shared protocol that supports enhanced management of maintenance operations between the host system and memory system, such as maintenance operations to resolve error conditions at a physical address of a memory system. In some examples, a memory system may initiate maintenance operations based on detections performed at the memory system, and the memory system may provide a maintenance indication for the host system. In some examples, a host system may initiate maintenance operations based on detections performed at the host system. In various examples, the described maintenance signaling may include capability signaling between the host system and memory system, status indications between the host system and memory system, and other maintenance management techniques.

Methods, systems, and devices for reporting control information errors are described. A state of a memory array may be monitored during operation. After detecting an error (e.g., in received control information), the memory device may enter a first state (e.g., a locked state) and may indicate to a host device that an error was detected, the state of the memory array before the error was detected, and/or at least a portion of a control signal carrying the received control information. The host device may diagnose a cause of the error based on receiving the indication of the error and/or the copy of the control signal. After identifying and/or resolving the cause of the error, the host device may transmit one or more commands (e.g., unlocking the memory device and returning the memory array to the original state) based on receiving the original state from the memory device.

A memory device comprises a memory bank comprising a plurality of addressable memory cells, wherein the memory bank is divided into a plurality of segments. Further, the device comprises a cache memory operable for storing a second plurality of data words, wherein each data word of the second plurality of data words is either awaiting write verification associated with the memory bank or is to be re-written into the memory bank. The cache memory is divided into a plurality of primary segments, wherein each primary segment of the cache memory is direct mapped to a corresponding segment of the plurality of segments, wherein each primary segment is sub-divided into a plurality of secondary segments, and wherein each of the plurality of secondary segments comprises at least one counter for tracking a number of entries stored therein.
