Latest Patents

One of his latest patents is the Independently-controlled-gate SRAM. This invention provides an IG 7T FinFET SRAM, which adopts independently-controlled-gate super-high-VFinFETs to achieve a stacking-like property. This innovation effectively eliminates read disturb and half-select disturb. Additionally, it utilizes keeper circuits and read control voltage to reduce leakage current of the bit lines during read operations. Furthermore, this invention addresses the issue of read errors at low operation voltage, which is common in conventional 6T SRAM designs.

Another notable patent is the Schmitt trigger-based FinFET SRAM cell. This invention features an 8-FinFET structure, where a FinFET has the functions of two independent gates. The new SRAM cell design uses only 8 FinFETs per cell, compared to the 10-FinFET structure in previous works. As a result, this design saves chip area and increases chip density. Moreover, it effectively resolves the conventional problem of read errors in 6T SRAM cells at low operating voltages.
