  • Publication number: 20240386962
    Abstract: A memory apparatus and method of operation are provided. The apparatus includes memory cells each connected to word lines and disposed in memory holes. The memory holes are arranged in rows comprising strings which are grouped into blocks comprising a first plane and a second plane. A control means is configured to program memory cells of the first plane and the second plane connected to one of the word lines using iterations of a program operation. The control means terminates programming of the first plane prior to completing programming of the first plane in response to determining the first plane programs slower than the second plane by a predetermined number of the iterations of the program operation. The control means adjusts the predetermined number of the iterations based on an additional verify iteration performed on at least some of the memory cells beyond the iterations of the program operation.

  • Patent number: 12132574
    Abstract: This application provides methods and apparatus for sending feedback information. By binding a BAR-BA feedback manner, that is, first a request and then a feedback, when it is determined that data retransmission is performed by using a hybrid automatic repeat request (HARQ) mechanism, duration of an acknowledgment operation performed by a data receive end on retransmitted data may be increased. Alternatively, the receive end estimates duration required for feeding back a receiving status of the retransmitted data, and feeds back the duration to a transmit end. The transmit end may therefore adaptively adjust duration of the retransmitted data based on a feedback capability of the receive end, to ensure that the feedback of the receive end on the receiving status of the retransmitted data is within a short inter-frame space (SIFS).

  • Publication number: 20240348529
    Abstract: This application is applicable to a multi-link group addressed traffic transmission method and an apparatus. A first access point (AP) of an AP multi-link device (MLD) sends group addressed traffic indication information indicating whether each AP of other APs of the AP MLD has a group addressed traffic, so that a station (STA) can learn whether the multiple APs have a group addressed traffic. In this way, each STA of the STA MLD does not need to listen to each AP whether each AP has a group addressed traffic. This reduces power consumption of the STA MLD. This application may be applied to a wireless local area network system that supports an IEEE 802.11ax next-generation Wi-Fi EHT protocol, for example, 802.11 series protocols such as 802.11be.

  • Publication number: 20240312538
    Abstract: A non-volatile memory system is configured to perform a multiplane erase process that concurrently erases groups of memory cells in multiple planes. Based on that multiplane erase process, the memory system determines that a first group of memory cells in a first plane of the multiple planes is slow to erase. As a result, the system will perform one or more multiplane erase processes for the groups of memory cells in multiple planes without erasing the first group of memory cells in the first plane as part of the multiplane erase process(es).
