摘要： An electronic device includes a functional unit and a current compensation unit. The functional unit operates based on a power supplied by an external host through power supply lines and generates a control signal based on an amount of power consumption of the functional unit. The current compensation unit compensates a change in a power supply current based on the control signal, where the power supply current is a current flowing through the power supply lines.

摘要： A row decoder circuit includes a decoding unit and first and second wordline driving units. The decoding unit generates a first driving signal and a second driving signal based on a selection signal and wordline voltages. A voltage level of the first driving signal and a voltage level of the second driving signal depend on an operation mode. The first wordline driving unit is connected to a first wordline and outputs one of the first driving signal and the second driving signal as a first wordline driving signal based on first driving control signals. The second wordline driving unit is connected to a second wordline and outputs one of the first driving signal and the second driving signal as a second wordline driving signal based on second driving control signals.

摘要： Provided are a semiconductor device and a method for compensating for a voltage drop of a bit line. The semiconductor device includes at least one monitoring bit line and at least one main memory bit line, and monitors a voltage of the at least one monitoring bit line after a precharging operation and supplies a predetermined compensation current to the at least one monitoring bit line and the at least one main memory bit line based on a monitoring result. Accordingly, it is possible to precisely compensate for a voltage drop occurring in the main memory bit line due to under precharge or leakage current, thereby preventing unnecessary compensation current from being supplied. Therefore, it is possible to stably perform a read operation of the semiconductor device.
