    Abstract: A method of operating a semiconductor memory device is disclosed. The method may include receiving an access command, applying a first voltage to a selected word line of the semiconductor memory device for a period of time in response to receiving the access command, applying a second voltage to word lines adjacent to the selected word line before and after the period of time, and applying a third voltage to the word lines adjacent to the selected word line for the period of time, a voltage level of the third voltage greater than the second voltage. The applying the third voltage may occur when the semiconductor memory device is operated at a temperature below the predetermined temperature.

    Abstract: Disclosed is a level shifter. The level shifter includes a level shifting circuit, a first adjusting circuit, and a second adjusting circuit. The level shifting circuit determines whether to output a first current from a supply voltage line to an output node based on a voltage level of a first node and determines whether to output a second current from the supply voltage line to a third node based on a voltage level of a second node. The first adjusting circuit blocks an output of a third current from the third node to the first node when a clock signal having a first voltage level is received. The second adjusting circuit outputs a fourth current from the first node to a ground voltage line when the clock signal having the first voltage level is received.

    Abstract: A semiconductor memory device includes a memory cell array, a data inversion/mask interface and a write circuit. The data inversion/mask interface receives a data block including a plurality of unit data, each of the plurality of unit data having a first data size, and the data inversion/mask interface selectively enables each data mask signal associated with each of the plurality of unit data based on a number of first data bits in a second data size of each unit data. The second data size is smaller than a first data size of the unit data. The write circuit receives the data block and performs a masked write operation that selectively writes each of the plurality of unit data in the memory cell array in response to the data mask signal.
