Patent number: 11948617Abstract: 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.Type: GrantFiled: February 22, 2022Date of Patent: April 2, 2024Assignee: Micron Technology, Inc.Inventor: Dmitri A.
