BITLINE PRECHARGE VOLTAGE GENERATOR, SEMICONDUCTOR MEMORY DEVICE HAVING THE SAME AND METHOD OF TRIMMING BITLINE PRECHARGE VOLTGAE

摘要

PURPOSE: A bitline precharge voltage generator, a semiconductor memory device having the same and a method of trimming bitline precharge voltage are provided to minimize bitline precharge voltage distribution by trimming a precharge voltage level through fuse. CONSTITUTION: A bit line precharge voltage generator(10) comprises a bit line precharge voltage supply unit(100) The bit line precharge voltage generator comprises a leakage trimming unit(200) The bit line precharge voltage generator comprises a monitoring unit(300) The leakage trimming unit provides the leakage current to an output node. The bit line precharge voltage is located in the edge area of a dead zone. The bit line precharge voltage supply unit supplies bit line precharge voltage to the output node.
