Bit cell and integrated circuit device including the same

A bit cell comprising:

• a read port comprising a read pass transistor and a read pull-down transistor;
• and
• a write port comprising a first pass transistor, a second pass transistor, a first pull-down transistor, a second pull-down transistor, a first pull-up transistor, and a second pull-up transistor,
• wherein the read pass transistor, the read pull-down transistor, the first pass transistor, and the first pull-down transistor share one active region.

An integrated circuit device comprising:

• a bit cell including a read port and a write port, comprising:
• a plurality of active regions comprising a first active region, a second active region, a third active region, and a fourth active region, which are spaced apart from each other in parallel in a first direction and extend in a second direction perpendicular to the first direction;
• and
• a plurality of gates comprising a first gate, a second gate, a third gate, and a fourth gate, which are spaced apart from each other in parallel in the second direction, extend in the first direction, and are arranged in at least one of the plurality of active regions to each form a transistor,
• wherein the read port comprises a read pass transistor and a read pull-down transistor,
• the write port comprises a first pass transistor, a second pass transistor, a first pull-down transistor, a second pull-down transistor, a first pull-up transistor, and a second pull-up transistor, and
• the read pass transistor, the read pull-down transistor, the first pass transistor, and the first pull-down transistor share one active region.
