Latest Patents
Ju-Seok Lee's latest patents include a non-volatile memory device that features a feedback circuit and a precharge switching transistor. This innovative device generates a feedback signal based on the voltage level of a bitline during a precharge operation. The precharge switching transistor, responding to the feedback signal, effectively controls the precharge current for the bitline. This advancement allows for an increased speed in the precharge operation and reduces the mismatch of bias signals across multiple bitlines.
Another notable patent is for a flash memory device that reduces noise in the common source line. This device controls the common source line voltage and implements a program verify method. A series of memory cells is connected between a bit line and the common source line. The data input/output circuit, linked to the bit line, is designed to store data intended for programming in a selected memory cell. During the program verify operation, the data input/output circuit maintains the data to be programmed and decreases noise in the common source line by selectively precharging the bit line based on the data.
