    Abstract: Apparatuses and methods for forcing memory cell failures in a memory device are disclosed. An example apparatus includes a column disable control circuit coupled to a plurality of column latch sets to receive match signals and associated column plane addresses, the column disable control circuit configured to provide redundant column select signals and column plane masking signals based on the match signals and associated column plane addresses, the column disable control circuit further configured to provide the redundant column select signal and the column plane masking signal corresponding to an active match signal and associated column plane address from a designated column latch set when a disable memory test mode is enabled to cause one or more memory cells of main memory to fail.

    Abstract: Apparatuses and methods for refreshing memory cells of a semiconductor device are described. An example apparatus includes: a memory cell array including a plurality of memory groups each having a plurality of memory cells, the memory groups being selected by mutually different addresses; a first control circuit periodically executing a refresh operation on the memory groups in response to a first refresh command; and a second control circuit setting a cycle of executing the refresh operation by the first control circuit. The second control circuit sets the cycle to a first cycle until executing the refresh operation to all the memory groups after receiving the first refresh command, and the second control circuit sets the cycle to a second cycle that is longer than the first cycle after executing the refresh operation to all the memory groups.
