Semiconductor device and semiconductor memory apparatus including the semiconductor device

A semiconductor memory apparatus comprising:

• a main circuit component comprising a core circuit component;
• and
• a spare circuit component comprising a plurality of spare elements, and the spare circuit component electrically coupled to the main circuit component to change a function of the main circuit component, wherein each of the plurality of spare elements is configured to comprises a cutoff part to block a source voltage supply,
• wherein the cutoff part of a spare element electrically coupled to the main circuit component for a change in the function of the main circuit component is electrically coupled to a source voltage supply terminal, and
• wherein each of the spare elements comprises:
• at least one gate line traversing an active area formed on a semiconductor substrate;
• a source line formed on one side of each of the at least one gate line, and comprising the cutoff part;
• a drain line formed on the other side of each of the at least one gate line;
• and
• the cutoff part configured to electrically separate the source line and a source voltage supply terminal.

A spare element comprising:

• a first line provided with a cutoff part;
• a second line;
• and
• a logic circuit component formed between the first line and the second line,
• wherein the first line is separated from a source voltage supply terminal by the cutoff part,
• the cutoff part of the spare element is electrically coupled to a source voltage supply terminal when the spare element is selected for changing a function of a main circuit component, and
• wherein each of the spare elements comprises:
• at least one gate line traversing an active area formed on a semiconductor substrate;
• the first line formed on one side of each of the at least one gate line, and comprising the cutoff part;
• and
• the second line formed on the other side of each of the at least one gate line.
