The present invention discloses a communication device and a communication method capable of power calibration. The decision logic block of the tone detector uses the roll-off characteristics of the filter in conjunction with background noise to determine a threshold passfail for any tone that has deviated excessively from its nominal value. The memory performs a write operation for writing data to a memory cell corresponding to the write pointer and a read operation for reading data from a memory cell corresponding to the read pointer. Still further provided by the invention are methods for producing soybean plants by crossing the soybean variety 01045798 with itself or another soybean variety and plants produced by such methods. The insulation property of the WL-CSP can be monitored with enhanced accuracy by measuring a resistance value between solder terminals electrically connected to the swirl-shaped TEG pattern. A bit line program voltage is applied to at least one selected bit line and a bit line program-inhibition voltage is applied to at least one unselected bit line.
