  • Patent number: 12147297
    Abstract: A memory address generation device for a test mode comprises row and column address random number counters and a control unit. The row address random number counter receives a counting signal to update a first count value, generates a row address random number based on the first count value, and outputs a row address to the memory. The column address random number counter receives the counting signal to update a second count value, generates a column address random number based on the second count value, and outputs a column address to the memory. The control unit controls the test mode and sets the first/second count value. A difference value between the currently and previously generated row addresses is greater than or equal to 2, and a difference value between the currently and previously generated column addresses is greater than or equal to 2.
