The magnetoresistive effect element comprises a first ferromagnetic layer 50, a nonmagnetic layer 52 formed on the first ferromagnetic layer 50, a second ferromagnetic layer 54 formed on the nonmagnetic layer 52, and a sidewall insulating film 64 formed on the side wall of the second ferromagnetic layer 54. The end of the first ferromagnetic layer 50 is aligned with the end of the sidewall insulating film 64. Whereby the disalignment between the first ferromagnetic layer and the second ferromagnetic layer can be prevented.

The disclosure provides a NAND flash memory and a reading method thereof, which may read a negative threshold value of a memory cell without using a negative-voltage-generating circuit. The disclosed NAND flash memory includes a sense amplifier, a bit line selecting circuit and an array having a plurality of NAND string units. The disclosed NAND flash memory includes a ΔV supplying portion element that applies a positive voltage to a source line, a P well formed with a selected memory cell, and a non-selected bit line which is adjacent to a selected bit line, within a predetermined time period, after the selected bit line is pre-charged and during a reading process.

The invention relates to a multifunctional surveying and mapping pen which comprises a main pen, an auxiliary pen, a straight ruler and a scale sleeve. The main pen comprises a main pen point, a main pen upper shell and a main pen lower shell. The auxiliary pen comprises an auxiliary pen point, an auxiliary pen upper shell and an auxiliary pen lower shell. The straight ruler is slotted, and an opening is formed in one end of the straight ruler. The main pen point is used as a supporting point for surveying and mapping, and the auxiliary pen point is used for drawing. Slots are formed in the circumferential faces of the main pen and the auxiliary pen along the axial line of the main pen and the axial line of the auxiliary pen respectively, wherein the circumferential faces are the same in height, therefore, the two pens can be embedded into a whole through the straight ruler and can be separated, the pens slide in the straight ruler, and the function of surveying and mapping a straight line is achieved. The main pen is used as a rotation center, the auxiliary pen can be fixed to any position of the straight ruler through the rotation of a threaded knob, the auxiliary pen is driven by the straight ruler to rotate, and then an angle can be determined through the scale sleeve clamped on the main pen, so that the function of surveying and mapping any circles, arcs, sectors, radiuses and angles is achieved. The multifunctional surveying and mapping pen has the advantages of being simple in structure, safe to use, low in cost and easy to operate, and both drawing quality and drawing efficiency are improved.
