Bit line precharge circuit having precharge elements outside sense amplifier

摘要

A bit line precharge circuit capable of improving bit line precharge operation includes a first precharge element for precharging a first bit line in response to a first precharge signal, a precharge unit for precharging second and third bit lines in response to a second precharge signal, and a second precharge element for precharging a fourth bit line in response to a third precharge signal.
