Abstract

A semiconductor memory apparatus may include a refresh counting portion configured to count the number of times a refresh signal is received by the refresh counting portion, and configured to generate a smart refresh enable signal when the number of times the refresh signal is received by the refresh counting portion reaches a predetermined number and an address arithmetic portion configured to latch an address, and, when the smart refresh enable signal is enabled, configured to perform an arithmetic operation of addition and subtraction on the latched address and output a result of the arithmetic operation as an arithmetic address. The semiconductor memory apparatus may also include an address selection portion configured to output one of the arithmetic addresses and one of the addresses as a selection address in response to the smart refresh enable signal.
