ABSTRACT:
A semiconductor memory device is provided that can support a per-bank refresh as well as an all-bank refresh and a self refresh. The semiconductor memory device includes an address counting unit for counting a bank address signal of a specific bank and row address signals of the specific bank in response to a control signal including refresh mode information when a per-bank refresh command is received, and for counting row address signals in response to the control signal when an all-bank refresh command or a self refresh command is received.
