  • Publication number: 20240126692
    Abstract: Memory devices and systems with post-packaging master die selection, and associated methods, are disclosed herein. In one embodiment, a memory device includes a plurality of memory dies. Each memory die of the plurality includes a command/address decoder. The command/address decoders are configured to receive command and address signals from external contacts of the memory device. The command/address decoders are also configured, when enabled, to decode the command and address signals and transmit the decoded command and address signals to every other memory die of the plurality. Each memory die further includes circuitry configured to enable, or disable, or both individual command/address decoders of the plurality of memory dies. In some embodiments, the circuitry can enable a command/address decoder of a memory die of the plurality after the plurality of memory dies are packaged into a memory device.

  • Patent number: 11670358
    Abstract: Memory devices and systems with adjustable through-silicon via (TSV) delay, and associated methods, are disclosed herein. In one embodiment, an apparatus includes a plurality of memory dies and a TSV configured to transmit signals to or receive signals from the plurality of memory dies. The apparatus further includes circuitry coupled to the TSV and configured to introduce propagation delay onto signals transmitted to or received from the TSV. In some embodiments, the apparatus includes additional circuitry configured to activate, deactivate, adjust at least a portion of the circuitry, or any combination thereof, to alter the propagation delay. In this manner, the apparatus can align internal timings of memory dies of the plurality of memory dies.

  • Publication number: 20230037145
    Abstract: Memory devices and systems with configurable die refresh stagger, and associated methods, are disclosed herein. In one embodiment, a memory system includes two or more memory dies. At least one memory die includes a fuse array storing refresh information that specifies a refresh group of the memory die. In these and other embodiments, at least one memory die includes a refresh group terminal and refresh group detect circuitry electrically connected to the refresh group terminal. The at least one memory die is configured to detect a refresh group of the memory die and to delay its refresh operation by a time delay corresponding to the refresh group. In this manner, refresh operations of the two or more memory dies can be staggered to reduce peak current demand of the memory system.

  • Patent number: 11393790
    Abstract: Memory devices and systems with TSV health monitor circuitry, and associated methods, are disclosed herein. In one embodiment, a memory device includes a plurality of memory dies, a plurality of through-silicon vias (TSVs) in electrical communication with the memory dies; and circuitry. In some embodiments, the circuitry is configured to electrically couple a pair of TSVs of the plurality of TSVs to form a passive circuit. For example, the circuitry can activate a transistor electrically positioned between TSVs of the pair of TSVs to electrically couple the pair of TSVs. In these and other embodiments, the circuitry applies a test voltage to the pair of TSVs using the passive circuit to determine whether a TSV of the pair of TSVs includes degradation.

  • Patent number: 11250890
    Abstract: Memory devices and systems with configurable die powerup delay, and associated methods, are disclosed herein. In one embodiment, a memory system includes two or more memory dies. At least one memory die has a powerup group terminal and powerup group detect circuitry. The powerup group detect circuitry is configured to detect a powerup group assigned to the at least one memory die. The at least one memory die is configured to delay its powerup operation by a time delay corresponding to the powerup group to which it is assigned. In this manner, powerup operations of the two or more memory dies can be staggered to reduce peak current demand of the memory system.
