摘要： A semiconductor memory device includes a memory cell array, a bit-line switch, a block switch, and a column decoder. 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.

摘要： A memory device includes first registers configured to store row addresses second registers configured to store an access count of each of the row addresses and generate a reference value flag signal when the access count is higher than a reference value. The memory device also includes a target row refresh controller configured to select one of the row addresses as a first target row address in response to the reference value flag signal, perform a first refresh operation on at least one first row address adjacent to the first target row address, randomly select one of the row addresses as a second target row address, and perform a second refresh operation on at least one second address adjacent to the second target row address. The second refresh operation may be performed when the reference value flag signal indicates that the access count is not greater than the reference value.

摘要： A method of testing a repair circuit of a memory device. The method may include storing first addresses in a first register of the repair circuit, wherein the first register is configured to store faulty addresses during a normal operation of the memory device, and the repair circuit is configured to perform a repair operation to replace the faulty addresses with redundancy addresses, storing test addresses in a second register of the repair circuit, wherein the test addresses are provided from a test host, outputting hit signals by comparing bit values of the addresses stored in the first register with bit values of the addresses stored in the second register, outputting repair enable signals based on the hit signals, and determining a status of a path where the repair enable signals are generated based on logic levels of the repair enable signals.
