Semiconductor module and semiconductor package

A semiconductor module capable of changing an operating characteristic thereof, the semiconductor module comprising:

• first and second transistors connected in series between a first potential and a second potential lower than the first potential and operating complementarily;
• a control circuit for controlling the first and second transistors;
• and
• an internal controller receiving a data signal including a set value of an operating characteristic from a controller provided externally to store the data signal in a memory and then transferring the set value of the operating characteristic to the control circuit,
• wherein the data signal is sent to the internal controller in the order of the set value of the operating characteristic and a specific trigger value specifying the timing of start of transfer of the set value of the operating characteristic to the control circuit,
• wherein the internal controller transfers the set vallie of the operating characteristic stored in the memory to the control circuit in timed relation to writing of the specific trigger value into the memory,
• wherein the control circuit includes first and second drivers for driving the respective first and second transistors and specifying the operating characteristic of the semiconductor module, and
• wherein the control circuit changes settings of the first and second drivers, based on the set value of the operating characteristic transferred from the internal controller, to thereby change the operating characteristic of the semiconductor module.
