Semiconductor device and method of driving the same

A method of driving a semiconductor device, comprising:

• for each refresh period, sequentially generating a plurality of memory address signals corresponding to a plurality of memory regions and generating a refresh pulse signal that toggles as many times as the number of the memory regions;
• for the each refresh period, activating an initialization pulse signal depending on a toggling number of the refresh pulse signal;
• for the each refresh period, generating a control pulse signal based on the refresh pulse signal and the memory address signals, and initializing the control pulse signal based on the initialization pulse signal;
• for the each refresh period, generating a row address signal based on the control pulse signal;
• and
• for the each refresh period, performing a refresh operation for the memory regions based on the row address signal.

A semiconductor device, comprising:

• a plurality of memory regions suitable for performing a refresh operation for each refresh period, based on a plurality of memory address signals respectively corresponding to the memory regions, and a row address signal;
• a control circuit suitable for activating a control pulse signal when the memory address signals are normally generated for the each refresh period;
• and
• a row address generation circuit suitable for generating the row address signal while changing the row address signal when the control pulse signal is activated.
