Abstract
A memory operating method includes selecting memory cells on a word line; transmitting potential levels of memory cells selected by the word line; pre-charging bit lines; amplifying the potential levels of the memory cells selected by the word line which are read to the bit lines; pre-charging a bus line on the basis of a pre-charge signal produced in synchronism with a clock signal; driving the bus line on the basis of a gate control signal; and transmitting the gate control signal so as not to drive the bus line when an enable signal is in an inactive state, and transmitting the gate control signal so as to drive the bus line on the basis of the potential of the bus line and output data of the amplifying means when the enable signal is in an active state.
