  • Patent number: 11954358
    Abstract: Methods, systems, and devices for cache management in a memory subsystem are described. An interface controller may include a first buffer and a second buffer. The interface controller may use the first and second buffers to facilitate operating a volatile memory as a cache for a non-volatile memory. During an access operation, the interface controller may use the buffer to transfer data between the volatile memory, non-volatile memory, and another device. In response to the access operation, the interface controller may use the second buffer to transfer second data from the volatile memory to the non-volatile memory.

  • Patent number: 11956955
    Abstract: A liner is formed laterally-outside of individual channel-material strings in one of first tiers and in one of second tiers.

  • Patent number: 11954055
    Abstract: Implementations of the present disclosure are directed to systems and methods for mapping point-to-point channels to packet virtual channels. A chip with an point-to-point interface converts point-to-point data to a packet format. The point-to-point channels are mapped to virtual channels of the packet transmission protocol. Information from multiple point-to-point channels may be combined in a single packet. Among the benefits of implementations of the present disclosure is that point-to-point devices may be connected to a packetized network without losing the benefits of separate channels for different types of communication. This allows existing point-to-point devices to communicate using a packetized network without internal modification or performance degradation.

  • Patent number: 11954035
    Abstract: Methods, systems, and devices for cache architectures for memory devices are described. For example, a memory device may include a main array having a first set of memory cells, a cache having a second set of memory cells, and a cache delay register configured to store an indication of cache addresses associated with recently performed access operations. In some examples, the cache delay register may be operated as a first-in-first-out (FIFO) register of cache addresses, where a cache address associated with a performed access operation may be added to the beginning of the FIFO register, and a cache address at the end of the FIFO register may be purged. Information associated with access operations on the main array may be maintained in the cache, and accessed directly (e.g., without another accessing of the main array), at least as long as the cache address is present in the cache delay register.
