An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs.
In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...
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 ]
This is known as "training" the magnet, and involves a type of material memory effect. One situation this is required in is the case of particle colliders such as CERN 's Large Hadron Collider .
The default definition of magnetic remanence is the magnetization remaining in zero field after a large magnetic field is applied (enough to achieve saturation). [1] The effect of a magnetic hysteresis loop is measured using instruments such as a vibrating sample magnetometer ; and the zero-field intercept is a measure of the remanence.
Avoid storing your credit card near magnets or other magnetic items. If your purse or wallet has a magnet on it, ensure the magnetic strip on your card faces away from the magnet to help avoid damage.
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 ...
