  • Patent number: 12034860
    Abstract: Methods, systems, and devices for memory write access control are described. In some examples, memory systems may include storage that is access-protected (e.g., write access protected). To enable access to the protected storage, a server node may communicate a command to the memory system that is signed with a private key that is inaccessible to the memory system. They memory system may verify the command using a public key and may enable access to the protected storage. Access commands associated with the protected storage may be processed until access to the protected storage is disabled.

  • Patent number: 12035543
    Abstract: Methods and apparatuses for a cross-point memory array and related fabrication techniques are described. The fabrication techniques described herein may facilitate concurrently building two or more decks of memory cells disposed in a cross-point architecture. Each deck of memory cells may include a plurality of first access lines (e.g., word lines), a plurality of second access lines (e.g., bit lines), and a memory component at each topological intersection of a first access line and a second access line. The fabrication technique may use a pattern of vias formed at a top layer of a composite stack, which may facilitate building a 3D memory array within the composite stack while using a reduced number of processing steps. The fabrication techniques may also be suitable for forming a socket region where the 3D memory array may be coupled with other components of a memory device.

  • Patent number: 12033716
    Abstract: Methods, systems, and devices for inductive energy harvesting and signal development for a memory device are described. One or more inductors may be included in or coupled with a memory device and used to provide current for various operations of the memory device based on energy harvested by the inductors. An inductor may harvest energy based on current being routed through the inductor or based on being inductively coupled with a second inductor through which current is routed. After harvesting energy, an inductor may provide current, and the current provided by the inductor may be used to drive access lines or otherwise as part of executing one or more operations at the memory device. Such techniques may improve energy efficiency or improve the drive strength of signals for the memory device, among other benefits.

  • Patent number: 12027213
    Abstract: Methods, systems, and devices for determining offsets for memory read operations are described. In response to a threshold quantity of pages failing initial reads but being successfully read using a same reference adjustment during re-reads, the offset responsible for the adjustment may be used as a first-applied offset for subsequent re-reads or a baseline offset for subsequent initial reads. After the initial reads begin using the reference adjustment, if a threshold quantity of pages fail initial reads, the offset used for the initial read may be adjusted to be the offset used to perform the successful re-reads. If an updated offset to use a baseline is not identified, the baseline offset may be cleared so the original reference may again be used without adjustment for initial reads.
