Semiconductor module includes semiconductor chip initialized by reset signal

A semiconductor device comprising:

• a motherboard;
• a semiconductor module mounted on the motherboard;
• and
• a controller mounted on the motherboard and supplying a reset signal to the semiconductor module,
• wherein the semiconductor module comprises:
• a plurality of semiconductor chips each including a reset terminal to which the reset signal is supplied, and an internal circuit that is initialized based on the reset signal;
• and
• a module substrate on which the semiconductor chips are mounted,
• wherein the module substrate comprises a reset signal line connected commonly to the reset terminals of the semiconductor chips, and an anti-resonance element connected to the reset signal line.

A semiconductor module comprising:

• a module substrate;
• first and second signal lines provided along each other on the module substrate;
• a semiconductor chip that is mounted on the module substrate and to which first and second signals are supplied through the first and second signal lines, respectively;
• and
• an anti-resonance element connected to the first signal line, wherein
• the first signal is activated to a first logic level at a time of start-up and fixed to a second logic level during a normal operation after the start-up,
• the second signal changes between the first logic level and the second logic level during the normal operation, and
• the anti-resonance element fixes the first signal to the second logic level to prevent periodic changes of the second signal during the normal operation from causing resonances on the first signal line due to crosstalk from the second signal line to the first signal line.
