the vertical parity bits being arranged in a row separate from the rows of horizontally contiguous
bytes of data;
each of the vertical parity bits relating to a corresponding one of the subset set of columns in
which at least one bit of data is stored;
each of the vertical parity bits being generated from the data stored in the corresponding
column of data to which the vertical parity bit relates, and each of the vertical parity bits reflecting parity
of the corresponding column of data;
wherein at least one byte of the data is accessed by an address and checked for horizontal
parity;
wherein when the horizontal parity of at least one of the bytes shows an error exists, a row
location of the error is determined by the address and a vertical parity check is run for the at least one
of the bytes addressed to determine a column location of the error, the row location and the column
location defining a particular bit location of the error.
