    Abstract: The semiconductor memory device includes a memory cell array and an error correction code (ECC) circuit. The memory cell array is divided into a first memory region and a second memory region. Each of the first and second memory regions includes a plurality of pages each page including a plurality of memory cells connected to a word line. The ECC circuit corrects single-bit errors of the first memory region using parity bits. The first memory region provides a consecutive address space to an external device by correcting the single-bit errors using the ECC circuit and the second memory region is reserved for repairing at least one of a first failed page of the first memory region or a second failed page of the second memory region.

    Abstract: A semiconductor memory device includes a control logic and a memory cell array in which a plurality of memory cells are arranged. The memory cell array includes a plurality of bank arrays, and each of the plurality of bank arrays includes a plurality of sub-arrays. The control logic controls an access to the memory cell array based on a command and an address signal. The control logic dynamically sets a keep-away zone that includes a plurality of memory cell rows which are deactivated based on a first word-line when the first word-line is enabled. The first word-line is coupled to a first memory cell row of a first sub-array of the plurality of sub-arrays. Therefore, increased timing parameters may be compensated, and parallelism may be increased.

    Abstract: In a method of refreshing in a memory device having a plurality of pages, a candidate refresh address corresponding to a page scheduled to be refreshed after a monitoring period is generated. Whether an active command is processed for the candidate refresh address is monitored during the monitoring period. If an active command is processed for the candidate refresh address during the monitoring period, the scheduled refresh for that page is skipped. If no active command is processed for the candidate refresh address during the monitoring period, the scheduled refresh operation is performed.

    Abstract: A test method of the semiconductor memory device including a memory cell array and an anti-fuse array includes detecting failed cells included in the memory cell array; determining a fail address corresponding to the detected failed cells; storing the determined fail address in a first region of the memory cell array; and reading the fail address stored in the first region to program the read fail address in the anti-fuse array. According to the test method of a semiconductor memory device and the semiconductor memory system, since the test operation can be performed without an additional memory for storing an address, the semiconductor memory device and the test circuit can be embodied by a small area.
