    摘要: A writing method for a magnetic random access memory (MRAM) using a bipolar junction transistor is disclosed. The writing method is for use with the MRAM using the bipolar junction transistor including: a semiconductor substrate serving as a base of the bipolar junction transistor; an emitter and a collector of the bipolar junction transistor formed in an active region of the semiconductor substrate; an MTJ cell positioned in the active region between the emitter and the collector, separately from the emitter and the collector by a predetermined distance; a word line formed on the MTJ cell; a bit line connected to the collector; and a reference voltage line connected to the emitter. The writing method for the MRAM using the bipolar junction transistor writes data by applying current from the emitter to the collector, and changing a magnetization direction of a free ferromagnetic layer of the MTJ cell by a magnetic field generated due to the current. The magnetization direction can be varied in a shorter distance than a distance between the MTJ cell and the bit line, thereby reducing current consumption. It is thus possible to improve a property and reliability of the semiconductor device.

    摘要: A non-volatile memory device and a method for forming the same are disclosed, which relate to a ferroelectric memory device having non-volatile characteristics. The non-volatile memory device includes a control gate configured to receive a read voltage, an insulation film formed over the control gate, a metal layer formed over the insulation film, configured to include a channel region, and a drain region and source region at both ends of the channel region, a ferroelectric layer formed over the channel region of the metal layer, and a program and read gate formed over the ferroelectric layer. A write operation of data corresponding to a resistance state of the channel region is performed by changing polarity of the ferroelectric layer in response to a voltage applied to the program and read gate, the drain and source regions, and the control gate. A read operation of data is performed by sensing a current value changing with a polarity state of the ferroelectric layer on the condition that the read voltage is input to the control gate and a sensing bias voltage is input to one of the drain region and the source region.
