PRECHARGE SIGNAL GENERATION CIRCUIT

摘要

PURPOSE: A precharge signal generating circuit is provided to accurately generate a precharge signal by limiting an operation of a latch unit in a strobe activation section. CONSTITUTION: A lead driving unit(310) drives an inner node with a first voltage in response to a lead strobe if a corresponding address is applied in a precharge section. A latch unit(330) stores a value corresponding to the voltage of the inner node and drives the voltage of the inner node with a first voltage or a second voltage according to the stored value. The latch unit generates a precharge signal by using the stored value and dose not drive the inner node with a second voltage in a lead strobe activation section.
