Abstract: A magnetic tunnel junction (MTJ) device includes two magnetic tunnel junction elements and a magnetic shielding layer. The two magnetic tunnel junction elements are arranged side by side. The magnetic shielding layer is disposed between the magnetic tunnel junction elements. A method of forming said magnetic tunnel junction (MTJ) device includes the following steps. An interlayer including a magnetic shielding layer is formed. The interlayer is etched to form recesses in the interlayer. The magnetic tunnel junction elements fill in the recesses. Or, a method of forming said magnetic tunnel junction (MTJ) device includes the following steps. A magnetic tunnel junction layer is formed. The magnetic tunnel junction layer is patterned to form magnetic tunnel junction elements. An interlayer including a magnetic shielding layer is formed between the magnetic tunnel junction elements.

Abstract: A method for initializing an add-on card of a computer and a control chip capable of coupling with the add-on card is provided, wherein the chip has thereon a shadow register, the add-on card has thereon a configuration read-only memory. The method includes steps of loading basic configuration data stored in the configuration read-only memory and required for the operation of the chip to the chip, and storing the basic configuration data in the shadow register when a basic input/output system (BIOS) performs a configuration-data reading action from the configuration read-only memory, and initializing the chip in response to the basic configuration data.
