The memory cell array includes memory blocks coupled to at least one word-line and each of the memory blocks includes memory cells. The bit-line switch is connected between a first half local input/output (I/O) line of a first memory block and a second half local I/O line of the first memory block. The block switch is connected between the second half local I/O line of the first memory block and a first half local I/O line of a second memory block adjacent to the first memory block. The column decoder includes a repair circuit that controls connections by applying a first switching control signal to the bit-line switch and a second switching control signal to the block switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor memory device capable of increasing flexibility of a column repair operation","description":"A semiconductor memory device includes a memory cell array, a bit-line switch, a block switch, and a column decoder.
