A precharge signal generation circuit of a semiconductor memory apparatus may comprise a read/write precharge command generation section configured to delay a precharge command by a first delay time set in response to a control signal to generate one of a read precharge command and a write precharge command; and a read/write bank precharge address generation section configured to delay a bank column address strobe signal by a second delay time set in response to the precharge command delayed in the read/write precharge command generation section, and generate one of a read bank precharge address and a write bank precharge address.
