Patent number: 11887660Abstract: The present invention provides a pseudo dual-port memory. The pseudo dual-port memory includes a single-port memory, a multiplexer, a timing control circuit and an output circuit. The multiplexer is configured to sequentially output a first address and a second address to the single-port memory. The output circuit is configured to receive output data from the single-port memory to generate a first reading result corresponding to the first address and a second reading result corresponding to the second address. The output circuit includes a first sense amplifier and a second sense amplifier, wherein the first sense amplifier receives the output data to generate first data serving as the first reading result according to a first control signal, and the second sense amplifier receives the output data to generate second data serving as the second reading result according to a second control signal.Type: GrantFiled: August 24, 2022Date of Patent: January 30, 2024Assignee: MEDIATEK INC.Inventors: Yi-Ping Kuo, Yi-Te Chiu

Patent number: 11880607Abstract: A self-repair memory circuit includes a cell array, a controller, a row repair decoder, and a column repair decoder. The cell array includes rows and columns of memory cells. The controller receives an input indicating row repair or column repair, and a repair address shared by the row repair and the column repair of the cell array. The row repair decoder maps the repair address of a defective row to a redundant row of the cell array when the input indicates the row repair. The column repair decoder maps the repair address of a defective column to another column of the cell array when the input indicates the column repair.Type: GrantFiled: November 17, 2021Date of Patent: January 23, 2024Assignee: MEDIATEK SINGAPORE PTE. LTD.Inventors: Kim Soon Jway, Shu-Lin Lai, Yi-Ping Kuo

Patent number: 10176853Abstract: A pre-processing circuit is used for pre-processing a data-line voltage representative of a data output of a memory device. The pre-processing circuit includes a pre-charging circuit and a clamping circuit. The pre-charging circuit pre-charges a data line to adjust the data-line voltage at the data line that is coupled to the memory device. The clamping circuit clamps the data-line voltage to generate a clamped data-line voltage when the data-line voltage is pre-charged to a level that enables a clamping function of the clamping circuit, wherein the clamped data-line voltage is lower than a supply voltage of the pre-processing circuit. The clamping circuit includes a feedback circuit that feeds back a control voltage according to the data-line voltage at the data line, and further reduces its direct current (DC) leakage when the data-line voltage is clamped, wherein the clamping function of the clamping circuit is controlled by the control voltage.Type: GrantFiled: April 27, 2017Date of Patent: January 8, 2019Assignee: MEDIATEK INC.Inventors: Chi-Hao Hong, Dao-Ping Wang, Yi-Wei Chen, Yi-Ping Kuo, Shu-Lin Lai
