  • Publication number: 20250259660
    Abstract: Apparatuses for timing control in a write path are disclosed. An example apparatus includes: a clock input circuit that receives a clock signal and provides an internal clock signal; a command decoder that receives command signals and the internal clock signal, and provides an active write command signal when the command signals indicates a write operation; a write latency shifter that receives the write command signal, a latency value and a WICA value, adjusts timing of the write command signal responsive to the latency value and the WICA value, and provides a shifted write command signal; and a write DLL including a delay line that receives the shifted write command signal and provides a delayed write command signal. The write DLL provides the WICA value to set a propagation time from the clock input circuit to the write DLL to be a multiple of a period of the clock signal.

  • Publication number: 20250259679
    Abstract: A memory array comprising strings of memory cells comprises laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers directly above a conductor tier. Strings of memory cells comprise channel-material strings that extend through the insulative tiers and the conductive tiers. The channel-material strings directly electrically couple to conductor material of the conductor tier. Below the stack, an insulating tier is directly above the conductor tier and a metal-material tier is directly above the insulating tier. Conductive rings extend through the metal-material tier and the insulating tier to conductor material of the conductor tier. The conductive rings individually are around individual horizontal locations directly above which are individual of the channel-material strings. The channel-material strings directly electrically couple to the conductor material of the conductor tier through the insulating tier by the conductive rings.

  • Patent number: 12386616
    Abstract: Disclosed in some examples are systems, methods, devices, and machine-readable mediums to detect and terminate programmable atomic transactions that are stuck in an infinite loop. In order to detect and terminate these transactions, the programmable atomic unit may use an instruction counter that increments each time an instruction is executed during execution of a programmable atomic transaction. If the instruction counter meets or exceeds a threshold instruction execution limit without reaching the termination instruction, the programmable atomic transaction may be terminated, all resources used (e.g., memory locks) may be freed, and a response may be sent to a calling processor.

  • Patent number: 12388050
    Abstract: Apparatuses and methods for coupling semiconductor devices are disclosed. In a group of semiconductor devices (e.g., a stack of semiconductor devices), a signal is provided to a point of coupling at an intermediate semiconductor device of the group, and the signal is propagated away from the point of coupling over different (e.g., opposite) signal paths to other semiconductor devices of the group. Loading from the point of coupling at the intermediate semiconductor device to other semiconductor devices of a group may be more balanced than, for example, having a point of coupling at semiconductor device at an end of the group (e.g., a lowest semiconductor device of a stack, a highest semiconductor device of the stack, etc.) and providing a signal therefrom. The more balanced topology may reduce a timing difference between when signals arrive at each of the semiconductor devices.
