Error checking parity and syndrome of a block of data with relocated parity bits

A method for error checking, comprising:

• forming a matrix having a plurality of bit position columns and rows, wherein the bit position columns are equal in number to bits of a word length, wherein the word length is for each of a plurality of words of a data vector, and is configured for a serial transmission of the words of the data vector, the bit position columns being one each for each bit, and wherein the bit position rows are equal in number to syndrome bits, the bit position rows being one each for each syndrome bit;
• and
• allocating a portion of the bit position columns to parity bits within at least one of the words of the data vector, wherein the portion of the bit position columns allocated to the parity bits is one each for each of the parity bits.
