Abstract: An infrared heat source module is configured to minimize problems such as wrinkles or cracks in electrodes even if the patterns of a coated part and an uncoated part of the electrodes present in a current collector vary. The module improves a drying efficiency of the coated part of the current collector. An electrode using the infrared heat source module is manufactured by a process.

Abstract: Circuits and methods for repairing a column in repairing a row by using an adjacent block are disclosed. An adjacent block selecting fuse unit generates an adjacent block selecting signal in response to a column redundancy start signal. The adjacent block selecting signal determines whether to use either row repair lines of a block designated by an externally inputted block address or row repair lines of an adjacent block of the block. A fuse unit receives the column redundancy start signal, the adjacent block designating bit, the inverted adjacent block designating bit and a plurality block address bits in which the adjacent block designated bit and the inverted adjacent block designating bit are removed from the block address and the inverting block address, and outputs an output signal.
