Title: Synthetic antiferromagnetic structure for magnetoelectronic devices
Inventor: JASON ALLEN JANESKY
IPC: H01F10/32
Filed: 2003-11-12
Granted: 2009-10-11
Abstract: A nearly balanced synthetic antiferromagnetic (SAF) structure that can be advantageously used in magnetoelectronic devices such as a magnetoresistive memory cell includes two ferromagnetic layers and an antiferromagnetic coupling layer separating the two ferromagnetic layers. The SAF free layer has weakly coupled regions formed in the antiferromagnetic coupling layer by a treatment such as annealing, layering of the antiferromagnetic coupling layer, or forming the antiferromagnetic coupling layer over a roughened surface of a ferromagnetic layer. The weakly coupled regions lower the flop field of the SAF free layer in comparison to untreated SAF free layers. The SAF flop is used during the write operation of such a structure and its reduction results in lower power consumption during write operations and correspondingly increased device performance.

Filed: 2003-11-17
Granted: 2005-02-01
Abstract: An impedance matching circuit includes a plurality of latch circuits, each connected to one of a plurality of logic circuits. Each latch circuit has a first input commonly connected to a signal line and a second input connected to one of a plurality of non-overlapping digital clock signals. Approximately half of the maximum output resistance is compared with an external resistor and the result latched by a latch circuit corresponding to the most significant bit of the control signal, effectively halving the possible voltage range. A next latch circuit latches the second most significant bit of the control signal similarly, and a third latch circuit latches the remaining bit of the control signal. The control signal controls a binary weighted transistor array that adjusts input voltage. An output signal goes to an output register where it is used to control an output driver.
