Abstract
A row address control circuit of a semiconductor memory device including dynamic memory cells includes a test mode setting unit, an address counter and a row address generating unit. The test mode setting unit is configured to provide a test mode signal that indicates whether a test operation is performed or not, in response to a test command; the address counter is configured to generate a first address that increases gradually; and the row address generating unit is configured to selectively choose one of the first address and a second address as a refresh address based on the test mode signal, the second address being externally provided.
