摘要： The present disclosure includes methods and apparatuses that include write command overlap detection. A number of embodiments include receiving an incoming write command and comparing a logical address of the incoming write command to logical addresses of a number of write commands in a queue using a tree data structure, wherein a starting logical address and/or an ending logical address of the incoming write command and a starting logical address and/or an ending logical address of each of the number of write commands are associated with nodes in the tree data structure.

摘要： Methods, systems, and devices for data alignment for logical to physical table compression are described. A controller coupled with the memory array may receive a command to access a logical block address associated with a memory device. In some cases, a first portion of a physical address of the memory device associated with the logical block address may be identified. The controller may perform an operation on the logical block address included in the command and identify a second portion of the physical address based on performing the operation. The physical address of the memory device may be accessed based on identifying the first portion and the second portion.

摘要： A method for managing a readahead cache in a memory subsystem based on one or more active streams of read commands is described. The method includes receiving a read command that requests data from a memory component and determining whether the read command is part of an active stream of read commands based on a comparison of a set of addresses of the read command with one or more of (1) a command history table, which stores a set of command entries that each correspond to a received read command that has not been associated with an active stream, or (2) an active stream table, which stores a set of stream entries that each corresponds to active streams of read commands. The method further includes modifying a stream entry in the set of stream entries in response to determining that the read command is part of an active stream.

摘要： A method for managing power amongst a set of memory devices that are provided a peak power that is quantized into a set number of power tokens. The method includes determining that the first memory die is to change from a lower power state that requires a first number of tokens to a higher power state that requires a second number of tokens. The method further includes transmitting a message in response to determining that the sum of the second number and a third number of power tokens allocated to other memory devices in the set of memory devices satisfies a threshold number of power tokens. The message includes the second number and is transmitted on a bus that is shared by the set of memory devices.

摘要： Exemplary methods, apparatuses, and systems include a first die in a power network receiving, from each of a plurality of dice in the power network, a first activity state value indicating that the respective die is in a high current state, a second activity state value indicating that the respective die is a moderate current state, or a third activity state value indicating that the respective die is a low current state. The received activity state values include at least one second or third activity state value. The first die determines, using the received activity state values, a first sum of the activity state values. The first die further selects an activity state based upon the first sum and sends, to the plurality of dice, an activity state value corresponding to the selected activity state.

摘要： An example apparatus for sequential garbage collection can include a memory device including a plurality of memory blocks associated with a plurality of logical block addresses (LBAs). The example apparatus can include a controller coupled to the memory device. The controller can be configured to monitor a quantity of read operations and a quantity of write operations associated with a plurality of command sizes performed on a portion of the plurality of memory blocks. The controller can be configured to monitor a quantity of read operations and a quantity of write operations associated with a particular LBA. The controller can be configured to determine a type of garbage collection operation to perform based on the monitoring.

摘要： Apparatuses and methods can be related power down workload estimations using artificial neural networks. Workload estimation can include predicting a duration of a subsequent power down event of the memory device. A quantity of maintenance operations to be performed on the memory device, may be predicted based on the predicted duration of the subsequent power down event, when the memory device is powered on after the subsequent power down event using an artificial neural network. The quantity of maintenance operations may be performed on the memory device prior to the subsequent power down event of the memory device.
