Functional magnetic resonance imaging (fMRI) has intriguing implications for the study of memory in humans, however it can also be used in animal models. fMRI can be used to assess brain functionality in monkeys in the context of a variety of behavioral tasks. [26]
Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory. The information is accessed using one or more read/write heads.
Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. [ 1 ] [ 2 ] Drums were widely used in the 1950s and into the 1960s as computer memory . Many early computers, called drum computers or drum machines, used drum memory as the main working memory of the computer. [ 3 ]
The memory device and method of propagation were described in a paper presented at the 13th Annual Conference on Magnetism and Magnetic Materials, Boston, Massachusetts, 15 September 1967. The device used anisotropic thin magnetic films that required different magnetic pulse combinations for orthogonal propagation directions.
Magnetic memory may refer to: Magnetic storage, the storage of data on a magnetized medium; Magnetic-core memory, an early form of random-access memory; Remanence, or residual magnetization, the magnetization left behind in a ferromagnet after an external magnetic field is removed; Rock magnetism, the study of the magnetic properties of rocks ...
In computing, magnetic-core memory is a form of random-access memory. It predominated for roughly 20 years between 1955 and 1975, and is often just called core memory , or, informally, core . Core memory uses toroids (rings) of a hard magnetic material (usually a semi-hard ferrite ).
Magnetoresistive random-access memory (MRAM) is a type of non-volatile random-access memory which stores data in magnetic domains. [1] Developed in the mid-1980s, proponents have argued that magnetoresistive RAM will eventually surpass competing technologies to become a dominant or even universal memory . [ 2 ]
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track , later 9-track tape.
