ABSTRACT:
The present invention provides a repair fuse circuit capable of performing stable latch operation. The present invention improves the reliability of the repair fuse circuit using flash memory cells, by performing the initialization of the cross-coupled latch circuit at a high voltage level. The repair fuse circuit of a cross-coupled latch structure includes a voltage increasing element for temporally increasing voltage level of the cross-coupled latch circuit and a controller for controlling the voltage increasing element. As a result, the repair fuse circuit is initialized in a high logic state.
