Semiconductor device

A semiconductor device comprising:

• a logic block;
• and
• a switch block that can electrically connect the logic block to a first bus and to a second bus intersecting with the first bus,
• wherein the switch block includes multiple unit configurations, the unit configuration in the switch block having:
• a first line extending along a first direction;
• a second line placed above the first line, the second line extending along a second direction, the second direction intersecting with the first direction;
• a first variable resistance element placed between the first line and the second line, the first variable resistance element having one end electrically connected to the first line and another end electrically connected to the second line;
• a third line placed above the second line, the third line extending along the first direction;
• a second variable resistance element placed between the second line and the third line, the second variable resistance element having one end electrically connected to the second line and another end electrically connected to the third line;
• a fourth line placed above the third line, the fourth line extending along the second direction;
• and
• a third variable resistance element placed between the third line and the fourth line, the third variable resistance element having one end electrically connected to the third line and another end electrically connected to the fourth line.
