Title: Young-Uk Chang: Innovator in Memory Device Technology
Introduction
Young-Uk Chang is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the field of semiconductor memory technology, holding a total of 8 patents. His work focuses on enhancing the efficiency and reliability of memory devices.
Latest Patents
Among his latest patents is a memory device that includes a memory cell array and a control circuit. This innovative memory device features a normal region with a first failed block and a redundant region containing a first redundant block that replaces the failed block. The control circuit utilizes a mapping table to store replacement information, allowing it to access the first redundant block effectively. During testing, the control circuit writes '1' in the normal region and the first redundant block while writing '0' in the redundant region, except for the first redundant block. It also adds replacement information for a second failed block and second redundant block to the mapping table, verifying the replacement results based on data read from the memory cell array.
Another notable patent involves a semiconductor memory device designed to control the operation of a delay-locked loop (DLL) circuit. This device includes a DLL circuit that receives an external clock signal and performs a locking operation to achieve a locked state between the external and internal clock signals. The control unit ensures that the DLL circuit maintains this locked state during the auto-refresh operation, which is crucial for refreshing memory banks.
