发明名称 Anti-fuse repair control circuit and semiconductor device including DRAM having the same
摘要 In an anti-fuse repair control circuit, a semiconductor memory device is integrated into a multi-chip package to perform an anti-fuse repair. An anti-fuse repair control circuit includes a data mask signal input circuit, a cell address enable unit a repair enable unit, and a repair unit. The data mask signal input circuit receives and outputs a data mask signal upon receiving a test control signal for an anti-fuse repair. The cell address enable unit receives an anti-fuse repair address to enable a cell address of an anti-fuse cell to be repaired upon receiving the data mask signal outputted from the data mask signal input circuit. The repair enable unit codes the cell address and output a repair enable signal and a drive signal according to whether or not an anti-fuse cell corresponding to the cell address is enabled. The repair unit supplies a repair voltage to the anti-fuse cell when the repair enable signal, the address, and the drive signal are enabled.
