Latest Patents

One of Kyu Won Choi'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, a row decoder that selects a wordline of the memory cell, and a wordline predecoder that generates a 'predec' signal. This signal is crucial for generating a wordline voltage provided to the row decoder. The predecoder operates using both the first voltage and a second voltage, which is different 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 significant patent is for a pseudo dual port memory device. This device improves operating speed and increases stability. It 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 the sense amplifier based on control signals. Additionally, a precharge control signal generation circuit is connected to the column multiplexer, which generates a precharge control signal based on the read and write multiplexer control signals.
