  • Publication number: 20240404567
    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: 11948617
    Abstract: Methods, systems, and devices for a magnetic cache for a memory device are described. Magnetic storage elements (e.g., magnetic memory cells, such as spin-transfer torque (STT) memory cells or magnetic tunnel junction (MTJ) memory cells) may be configured to act as a cache for a memory array, where the memory array includes a different type of memory cells. The magnetic storage elements may be inductively coupled to access lines for the memory array. Based on this inductive coupling, when a memory value is written to or read from a memory cell of the array, the memory value may concurrently be written to a magnetic storage element based on associated current through an access line used to write or read the memory cell. Subsequent read requests may be executed by reading the memory value from the magnetic storage element rather than from the memory cell of the array.
