Abstract
A memory device having an on-chip ECC system includes an array of memory cells, some of which have wider transistors than others so that they have faster access speeds. Data bits are written into ordinary memory cells and the check bits are written into the faster cells in order to make up for the delay associated with the calculation of the check bits.
