ABSTRACT:
A semiconductor memory device having banks includes an address input path selection circuit in each of the banks, the address input path selection circuit including a signal input unit configured to selectively activate a Y-address input enable signal in response to a bank-specific read/write signal, and a latch unit configured to latch the Y-address input enable signal. The address input path selection circuit reduces circuit area by reducing delay elements and prevents malfunction by operating only in a bank active state.
