Latest Patents

One of Lichuan Zhao's latest patents is titled "Complementary metal oxide semiconductor circuit of memory device." This invention features a complementary metal oxide semiconductor (CMOS) circuit that includes a high-voltage functional circuit and an auxiliary clamping circuit. The high-voltage functional circuit comprises at least one MOS transistor, with one of its source or drain terminals connected to an input high-voltage. The output voltage of this circuit gradually increases to a maximum value when an enable signal is valid. The auxiliary clamping circuit is designed to clamp the voltage input to the MOS transistor during the rising phase of the output voltage, ensuring that the clamping voltage remains lower than the input high-voltage.

Another notable patent is "Three-dimensional memory devices with drain select gate cut and methods for forming and operating the same." This invention describes a 3D memory device that includes a memory stack, multiple memory strings, and bit line contacts. The memory stack consists of interleaved conductive and dielectric layers, with each memory string extending vertically through the stack. The conductive layers feature drain select gate (DSG) lines that control the drains of the memory strings, which are organized into regions that represent the minimum repeating unit of the memory stack.
