Abstract: An LSA circuit includes a first sensing transistor and a second sensing transistor connected in series between a local I/O line and a complementary local I/O line, a pre-sensing driver configured to drive an LSA sensing voltage to a connection node between the first sensing transistor and the second sensing transistor during a pre-sensing operation of the LSA circuit, and a main-sensing driver configured to drive the LSA sensing voltage to the connection node during a main-sensing operation of the LSA circuit. A driving strength of the pre-sensing driver is set to be weaker than a driving strength of the main-sensing driver, and the pre-sensing driver is driven before the main-sensing driver.
