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.
A memory diode, comprising a bottom electrode, an isolation layer, a memory layer, and a top electrode that are stacked from bottom to top, wherein the memory layer is formed by stacking germanium oxide, aluminum oxide, and hafnium oxide from bottom to top, and the bottom electrode is made of germanium.
A ternary content addressable memory based on a memory diode, wherein the ternary content addressable memory comprises a number of kernel units having functions of data storing, data erasing/writing, and data comparing;
The ternary content addressable memory based on the memory diode according to claim wherein when a data bit stored in the kernel unit is consistent with a search signal, it is in a match state (match), and when all kernel units on a same matching line are in the match state (match), the matching line outputs [0];
