Abstract

Methods and memory circuits for altering a magnetic direction of a magnetic memory cell using picosecond electric current pulses are disclosed. One method includes directing a first electric current pulse through the magnetic memory cell that includes a ferrimagnetic material layer to heat the ferrimagnetic material layer to toggle a magnetic direction of the ferrimagnetic material layer from a first magnetic direction to a second magnetic direction.

Device and methods for writing and erasing analog information in small memory units via voltage pulses

Patent El Gabaly Marquez, Farid; Talin, Albert Alec

Devices and methods for non-volatile analog data storage are described herein. In an exemplary embodiment, an analog memory device comprises a potential-carrier source layer, a barrier layer deposited on the source layer, and at least two storage layers deposited on the barrier layer. The memory device can be prepared to write and read data via application of a biasing voltage between the source layer and the storage layers, wherein the biasing voltage causes potential-carriers to migrate into the storage layers. After initialization, data can be written to the memory device by application of a voltage pulse between two storage layersmore »« less

System and method for dynamically allocating memory to hold pending write requests

Patent Farahani, Amin Farmahini; Roberts, David A.; Jayasena, Nuwan

A processing system employs a memory module as a temporary write buffer to store write requests when a write buffer at a memory controller reaches a threshold capacity, and de-allocates the temporary write buffer when the write buffer capacity falls below the threshold. Upon receiving a write request, the memory controller stores the write request in a write buffer until the write request can be written to main memory. The memory controller can temporarily extend the memory controller's write buffer to the memory module, thereby accommodating temporary periods of high memory activity without requiring a large permanent write buffer atmore » the memory controller.« less

Read/write head having a GMR sensor biased by permanent magnets located between the GMR and the pole shields

Patent Yuan, Samuel W [San Carlos, CA]; Rottmayer, Robert Earl [Fremont, CA]; Carey, Matthew J [San Jose, CA]

A compact read/write head having a biased giant magnetoresistive sensor. Permanent magnet films are placed adjacent to the giant magnetoresistive sensor operating in the current-perpendicular-to the-plane (Cpp) mode and spaced with respect to the sensor by conducting films. These permanent magnet films provide a magnetic bias. The bias field is substantial and fairly uniform across sensor height. Biasing of the giant magnetoresistive sensor provides distinguishable response to the rising and falling edges of a recorded pulse on an adjacent recording medium, improves the linearity of the response, and helps to reduce noise. This read/write head is much simpler to fabricatemore »« less

Skyrmion based universal memory operated by electric current

Patent Zang, Jiadong; Chien, Chia-Ling; Li, Yufan; ...

A method for generating a skyrmion, comprising: depositing a vertical metallic nanopillar electrode on a first side of a helimagnetic thin film, the helimagnetic thin film having a contact on a second side to provide a current drain; injecting a current through the vertical metallic nanopillar electrode to generate a rotating field; and applying a static upward magnetic field perpendicular to the helimagnetic thin film to maintain an FM phase background.

Magnetic memory using single domain switching by direct current

Patent Chung, Seok-Hwan; Hoffmann, Axel F.

A method for implementing miniaturization of magnetic random access memory (MRAM) and a magnetic memory using single domain switching by direct current are provided. The magnetic memory preferably includes a half-circle or U-shaped architecture with an exchange biasing pad, such as a FeMn exchange biasing pad that effectively generates a head-to-head magnetization configuration. The magnetic memory also includes nanometer scale notches in order to minimize magnetostatic interaction between a single domain memory element and the spin current sources and to effectively trap the magnetic domain wall. Reading the bit can be carried out by anisotropic magnetoresistance, or by other meansmore »« less
