Semiconductor device

A semiconductor device comprising:

• a first table including a plurality of driving patterns;
• a controller including the first table;
• and
• a driver that includes
• a second table including at least a first pattern and a second pattern of the plurality of the driving patterns in the first table,
• a control circuit,
• a generation circuit that generates a driving pulse based on the first pattern, and
• a drive circuit that drives a switch element by a voltage or a current based on the first pattern at a timing based on the driving pulse, wherein
• at a timing when the switch element is turned on or turned off,
• in a case where a change amount of first information of the switch element is less than a first threshold, the control circuit generates a correction value, and the generation circuit generates the driving pulse based on the first pattern and the correction value, and
• in a case where the change amount of the first information of the switch element is equal to or greater than the first threshold, the control circuit replaces the first pattern with the second pattern, and the generation circuit generates the driving pulse based on the replaced first pattern.
