    摘要: A memory apparatus includes a first memory bank, a second memory bank, a row decoder and repair circuit, and an input/output driver controller. The row decoder and repair circuit is coupled to the first and second memory banks in common. The row decoder and repair circuit generates a shared repair signal according to whether a word line disposed in a first memory bank is replaced with a word line disposed in a second memory bank. The input/output driver controller allows read or write operations for one of the first and second memory banks to be performed based on the shared repair signal and an operation signal.
