Latest Patents

One of his latest patents is a "Word line multi-selection circuit for a memory device." This innovation involves a semiconductor memory device, such as a DRAM, which includes a word line multi-selection circuit. A row decoder generates a word line selecting signal for selecting a read-out word line to read information from a selected memory cell. The word line selecting signal is also utilized to select a write-back word line used in the previous cycle to read cell information, which is then used in the current cycle to write back cell information. The circuit includes a register for temporarily storing the cell information read from the selected memory cell and for providing information read in the previous cycle to perform the write-back operation.

Another notable patent is for a "Semiconductor integrated circuit equipped with a test circuit." This integrated circuit device features multiple input/output terminals, an input terminal, and an internal circuit for receiving input data and outputting output data. The test circuit allows data exchange among the input/output terminals, the input terminal, and the internal circuit. It operates in both normal and test modes, enabling efficient data handling and testing capabilities.
