摘要： A content-addressable random access memory having magnetic tunnel junction-based memory cells and methods for making and using same. The magnetic tunnel junction has first and second magnetic layers and can act as a data store and a data sense. Within each cell, registered data is written by setting a magnetic orientation of the first magnetic layer in the magnetic tunnel junction via current pulses in one or more current lines. Input data for comparison with the registered data can be similarly set through the magnetic orientation of the second magnetic layer via the current lines. The data sense is performed by measuring cell resistance, which depends upon the relative magnetic orientation of the magnetic layers. Since data storage, data input, and data sense are integrated into one cell, the memory combines higher densities with non-volatility. The memory can support high speed, reduced power consumption, and data masking.

摘要： This magnetic memory with a thermally-assisted write, every storage cell of which consists of at least one magnetic tunnel junction, said tunnel junction comprising at least:one magnetic reference layer, the magnetization of which is always oriented in the same direction at the time of the read of the storage cell; one so-called “free” magnetic storage layer, the magnetization direction of which is variable; one insulating layer sandwiched between the reference layer and the storage layer. The magnetization direction of the reference layer is polarized in a direction that is substantially always the same at the time of a read due to magnetostatic interaction with another fixed-magnetization layer called the “polarizing layer”.

摘要： A matrix array of recording heads, wherein each head is independent from another both in terms of its magnetic circuit and excitation conductors. Each individual head has a planar magnetic circuit and an helical coil wrapped around the lower part of the magnetic circuit. The matrix array is collectively fabricated using full thin film technology on non-magnetic substrates. Preferably, the heads are aligned in an oblique lattice with the write gaps aligned along rows and offset by a constant value along columns. Each individual head is connected to the control electronics through interconnects to the backside of the wafer, allowing independent control of the write parameters. The die forming the device is shaped on its edges and top surface to optimize head/medium positioning and minimize wear.
