His work has been instrumental in advancing the efficiency and functionality of memory systems.

Latest Patents

One of Hyeong Cheol Kim's latest patents is a memory device that includes a predecoder and an operating method. This memory device comprises a memory cell that stores data based on a first voltage. It features a row decoder that selects a wordline of the memory cell based on this first voltage. Additionally, a wordline predecoder generates a 'predec' signal, which is essential for producing a wordline voltage for the row decoder. The predecoder operates using both the first voltage and a second voltage, which differs from the first. It receives a row address signal and an internal clock signal to adjust the operating timings of the memory device's elements. The predecoder performs a NAND operation on the row address signal and the internal clock signal, providing the generated “predec” signal to the row decoder.

Another notable patent is for pseudo dual port memory devices, which improve operating speed and stability. This device includes a memory cell, a pair of bit lines connected to the memory cell, a write driver, a sense amplifier, and a column multiplexer. The column multiplexer connects the bit lines to the write driver or sense amplifier based on control signals. A precharge control signal generation circuit is also included, which generates a precharge control signal based on the read and write multiplexer control signals. This innovation enhances the performance of memory devices significantly.
