    Abstract: A ternary content addressable memory and a two-port SRAM are provided and include a storage cell and two transistors. The storage cell includes a first active region, a second active region, a third active region, and a fourth active region, extending along a first direction, and a first gate line, a second gate line, a third gate line, and a fourth gate line extending along a second direction. The first gate line crosses the third active region and the fourth active region, the second gate line crosses the fourth active region, the third gate line crosses the first active region, and the fourth gate line crosses the first active region and the second active region. The transistors are electrically connected to the storage cell, and the transistors and the storage cell are arranged along the first direction.

    Abstract: A two-port ternary content addressable memory (TCAM) and layout pattern thereof, and associated memory device are provided. The two-port TCAM may include a first storage unit, a second storage unit, a set of first search terminals, a set of second search terminals, a first comparison circuit, a second comparison circuit, a first match terminal and a second match terminal, wherein the first comparison circuit is respectively coupled to the first storage unit, the second storage unit, the set of first search terminals and the first match terminal, and the second comparison circuit is respectively coupled to the first storage unit, the second storage unit, the set of second search terminals and the second match terminal. First search data and second search data may be concurrently inputted into the two-port TCAM for determining whether the first search data and the second search data match content data within the two-port TCAM.

    Abstract: A high-density semiconductor structure includes a substrate, a bit line and a first memory unit. The bit line, disposed on the substrate, has a first side and a second side. The first memory unit includes a first transistor, a first capacitor, a second transistor and a second capacitor. The first transistor disposed on the substrate has a first terminal and a second terminal. The first terminal connects the bit line. The first capacitor connects the second terminal of the first transistor. The second transistor disposed on the substrate has a third terminal and a fourth terminal. The third terminal connects the bit line. The second capacitor connects the fourth terminal of the second transistor. The first capacitor and the second capacitor are separated from the bit line in a direction perpendicular to an extending direction of the bit line and located on the first side of the bit line.

    Abstract: A stress memorization process including the following step is provided. A gate is formed on a substrate. A low-k dielectric layer with a dielectric constant lower than 3 is formed to entirely cover the gate and the substrate. A stress layer is formed to entirely cover the low-k dielectric layer. The stress layer and the low-k dielectric layer are removed. Moreover, a semiconductor structure including a contact etch stop layer is provided. A gate is disposed on a substrate. A porous layer entirely covers the gate and the substrate. A contact etch stop layer entirely covers the porous layer, wherein the thickness of the porous layer is thinner than the thickness of the contact etch stop layer.
