    Abstract: Voltage generating apparatus includes a positive temperature coefficient current generating module, a negative temperature coefficient current generating module, a fine-tune current module and a voltage output module. The function of the positive temperature coefficient current generating module and the negative temperature coefficient current generating module, which take advantage of characteristics of MOS devices operated in the sub-threshold region, is to generate a stable current of positive temperature coefficient and a stable current of negative temperature coefficient, respectively. The current fine-tune module increases or decreases output current of the negative temperature coefficient current generating module. The voltage output module sums two output currents of the positive temperature coefficient current generating module and the negative temperature coefficient current generating module and transforms the total current into output voltage that is stable under temperature and process variation.

    Abstract: A multi-level memory cell has a substrate, a first floating gate, a second floating gate and a control gate. A first doped region, a second doped region and a channel region located between the first doped region and the second doped region are provided in the substrate. The first floating gate is located over the channel region near the first doped region. The second floating gate is located over the channel region near the second doped region and isolated from the first floating gate. A control gate is located over the first and the second floating gates. When writing operations are proceeding, the bias voltages of the control gates are the same, and a constant bias voltage is provided on the first doped region or the second doped region depending on which binary states 11, 10, 01 or 00 are to write. Furthermore, the same bias voltage is used on the control gate during writing operation. Thus, the memory per unit chip area is enhanced and the peripheral circuits are simplified.
