    摘要: The present disclosure provides a semiconductor integrated circuit device and a manufacturing method therefor. In the device, an electrode in a resistive random-access memory (RRAM) cell is directly connected to a metal layer, thereby omitting the steps of filling a connection via with other metal materials (such as tungsten) and of polishing. The manufacturing process is hence simplified, and different degrees of depressions caused by polishing are correspondingly reduced. The uniformity of resistive performance of the RRAM and the quality of the semiconductor integrated circuit device are hence greatly improved. In addition, a resistive layer having a trench structure is formed by using a trench where an original connection via is located, thereby embedding the entire RRAM cell into the trench. The structure of the RRAM cell is more compact, a gap between RRAM cells is smaller, and the requirements for miniaturization and high density can thus be better met.

    摘要: The present disclosure discloses a ternary content addressable memory based on a memory diode, which includes a plurality of kernel units having functions of storing data, erasing/writing data, and comparing data; the kernel units are arranged in an array, all kernel units in a unit of row are connected to a same matching line, and all kernel units in a unit of column are connected to a same pair of complementary search signal lines; the kernel unit includes two memory diodes; top electrodes of a first memory diode and a second memory diode are respectively connected to a pair of complementary search signal lines, and bottom electrodes of the first memory diode and the second memory diode are connected to a same matching line. The present disclosure can greatly reduce a chip dimension of the ternary content addressable memory and reduce power consumption; the ternary content addressable memory of the present disclosure has a simple structure, which effectively simplifies a manufacturing process and reduces a manufacturing cost; the present disclosure provides and achieves a memory diode that is compatible with a standard CMOS process, which is suitable for currently rapidly developing semiconductor integrated circuits.
