Methods, systems, and apparatus for command scheduling in a memory subsystem according to a selected scheduling ordering are described.

Described apparatuses and methods control a voltage or a temperature of a memory domain to balance memory performance and energy use. In some aspects, an adaptive controller monitors memory performance metrics of a host processor that correspond to commands made to a memory domain of a memory system, including one operating at cryogenic temperatures. Based on the memory performance metrics, the adaptive controller can determine memory performance demand of the host processor, such as latency demand or bandwidth demand, for the memory domain. The adaptive controller may alter, using the determined performance demand, a voltage or a temperature of the memory domain to enable memory access performance that is tailored to meet the demand of the host processor. By so doing, the adaptive controller can manage various settings of the memory domain to address short- or long-term changes in memory performance demand.

Systems, methods, and apparatus related to a memory system that manages an interface for a volatile memory device and a non-volatile memory device to control memory system power. In one approach, a controller evaluates a demand on memory performance. If the demand of a current computation task needed by the host is high, a DRAM device is powered-up to meet the demand. Otherwise, if the non-volatile memory device is adequate to meet the demand, the DRAM memory is partially or fully-powered down to save power. In another approach, a task performed for a host device uses one or more resources of a first memory device (e.g., DRAM). A performance capability of a second memory device (e.g., NVRAM) is determined. A controller of the memory system determines whether the performance capability of the second memory device is adequate to service the task. In response to determining that the performance capability is adequate, the controller changes a mode of operation of the memory system so that one or more resources of the second memory device are used to service the task.

A memory device is set to a performance mode. Data item is received. The data item in a page of a logical unit of the memory device associated with a fault tolerant stripe is stored. A redundancy metadata update for the fault tolerant stripe is delayed until a subsequent media management operation.
