Latest Patents

Ren's latest patents include the Sb–Te–Ti phase-change memory material and the Ti–Sb2Te3 phase-change memory material. The Sb–Te–Ti phase-change thin-film material is designed for use in phase-change memory applications. This innovative material is created by doping an Sb–Te phase-change material with titanium, which forms bonds with both antimony and tellurium. The resulting chemical formula is SbTeTi, where specific ratios of x and y are maintained. This material exhibits improved crystallization temperature, enhanced retention, and better thermal stability. Additionally, the amorphous state resistance decreases while the crystalline state resistance increases, making it suitable for various phase-change memory applications.

The second patent focuses on a phase-change storage unit intended to replace traditional DRAM and FLASH technologies. This unit consists of a phase-change material layer and a cylindrical lower electrode. The design features a hollow cylinder or inverted conical frustum filled with a medium layer, which optimizes the phase-change material layer's thickness. This innovation leads to reduced operating power consumption, improved data holding capability, and increased operating speed.
