Abstract
A memory arrangement having a memory cell array, wherein each column is associated with a bit line and each row is associated with a word line, wherein the columns have first columns of memory cells that store useful data, and columns of memory cells of a second column type that store prescribed verification data, wherein during a read access operation the memory cells of at least the columns of memory cells of the second column type set the associated bit line to a value that corresponds to a logic combination of the values stored by the memory cells of the column of the second column type that belong to rows of memory cells addressed during the read access operation, and a detection circuit that is configured to, during a read access operation, detect whether a bit line associated with a column of memory cells of the second column type is set to a value that corresponds to the logic combination of values stored by memory cells of the column of the second column type of memory cells and whose values belong to different rows of memory cells.
