VOLTAGE RESETTING CIRCUIT FOR SEMICONDUCTOR MEMORY DEVICE USING OPTION FUSE CIRCUIT AND VOLTAGE RESETTING METHOD THEREOF

摘要

A voltage resetting circuit for a semiconductor memory device using an option fuse circuit and a method thereof are provided to improve yield of the semiconductor memory device by generating an internal voltage accurately. A plurality of option fuse circuits(310~314) includes a plurality of fuses, respectively. A fusing control circuit(200) generates a control signal selecting one of the fuses to each option fuse circuit by using a fuse option of a reset fuse. Each option fuse circuit adjusts the output several times by cutting the selected fuse.
