Abstract
An example apparatus may perform concurrent threshold voltage compensation in a memory array with distributed row redundancy. The example apparatus may include a row decoder configured to configured to, in response to a determination that the prime row address matches a defective prime row address, concurrently initiate a threshold voltage compensation operation on both of a prime row of the respective plurality of prime rows of memory cells of a first row section of the plurality of row sections corresponding to the prime row address and the respective redundant row of a second row section of the plurality of row sections. The row decoder may be further configured to stop an access operation associated with the prime row from proceeding based on a comparison of subset of match signals from either the first or second pluralities of row sections.
