摘要:
Apparatuses and methods for compressing data responsive to a plurality of memory accesses is described. An example compression circuit includes a comparator configured to compare data provided by a group of memory cells associated with a repair address. Each subset of one or more bits of the data is sequentially provided by the group of memory cells responsive to a respective memory access of a plurality of memory accesses. The example compression circuit further including an error bit latch coupled to the comparison circuit. The error bit latch configured to, responsive to an output received from the comparison circuit indicating an error, compress the data to an error bit by setting the error bit to an error detected state and latching the error bit having the error detected state.
