  • Publication number: 20250044965
    Abstract: Signaling indicative of a command to initialize a plurality of memory dies of a memory device can be received by the memory device. Initialization of a memory die of the memory device can be delayed, at the memory die and based at least in part on fuse states of an array of fuses of the memory die, by an amount of time relative to receipt of the signaling by the memory device. Delaying initialization of memory dies of the memory device in a staggered or asynchronous manner can evenly distribute power consumption of the memory dies so that the likelihood of an associated power spike is reduced or eliminated.

  • Patent number: 12197264
    Abstract: Methods, systems, and devices for power management for a memory device are described. For example, a memory device may include one or more memory dies and may be configured to operate using a first supply voltage and a second supply voltage. The first supply voltage may be associated with a first defined voltage range, and the second supply voltage may be associated with a second defined voltage range. The memory device may include a power management integrated circuit (PMIC) that is coupled with the one or more memory dies and provides the supply voltages to the one or more memory dies. The PMIC may be configured to provide, to the one or more memory dies, a first voltage that is within the first defined voltage range as the first supply voltage and a second voltage that is outside the second defined voltage range as the second supply voltage.

  • Publication number: 20240194239
    Abstract: Methods, apparatuses, and systems related to managing operations performed in response to refresh management (RFM) commands. A controller generates the RFM command for coordinating a refresh management operation targeted for implementation at an apparatus. The apparatus tracks refresh target set that includes refresh management target locations within the apparatus. According to the tracked refresh management target set, the apparatus selectively implements the targeted refresh management operation and/or a response operation in addition to or as a replacement for the targeted refresh management operation.

  • Publication number: 20240177761
    Abstract: Memory devices and systems with partial array refresh control over memory regions in a memory array, and associated methods, are disclosed herein. In one embodiment, a memory device includes a memory array having a first memory region and a second memory region. The memory device is configured to write data to the memory array in accordance with a programming sequence by initially writing data to unutilized memory cells of the first memory region before initially writing data to unutilized memory cells of the second memory region. The memory device is further configured to determine that the data stored on the first and/or second memory regions is not consolidated, and to consolidate at least a portion of the data by rewriting the portion of the data to physically or logically contiguous memory cells of the first memory region and/or the second memory region.

  • Publication number: 20240177743
    Abstract: Methods of optimizing the placement of memories in a memory device including a substrate and an electrical component, and associated devices and systems, are disclosed herein. A representative method includes first testing the memories to determine at least one parameter for each of the memories indicating an ability of the memory to process signals from the electrical component. The method can further include labeling each memory with a label based on the parameter, the labels including at least a first label and a second label. The first label can indicate that the memories with the first label are better able to process signals from the electrical component than the memories with the second label. The method can further include electrically coupling the memories to the substrate such that the memories with the second label are positioned closer to the electrical component than the memories with the first label.
