  • Publication number: 20260133906
    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.

  • Publication number: 20250328419
    Abstract: A memory device includes an off-lining logging circuit. The memory device detects errors in the memory array as well as one or more addresses which identify where in the array the error was located. The off-lining logging circuit counts errors in different portions of the array, such as sections and/or column planes, based on the addresses. If the count value crosses a threshold, the portion may be identified as a candidate for off-lining. In some examples, a host device may receive off-lining candidate address information from the memory and off-line the identified portions.

  • Publication number: 20250329372
    Abstract: A memory device logs telemetry information using a resistive element array. A telemetry logging circuit changes a resistance of one or more resistive elements in the array responsive to one or more commands, addresses, mode signals, or combinations thereof. The change to the resistance may be cumulative with other changes. For example if the resistive element is an antifuse, the resistance may decrease each time the information is logged. In some example embodiments, the memory may read out a resistance of one or more of the resistive elements to determine a telemetry value, which may be written to storage such as a mode register or SPD.

  • 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.

  • 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.
