Abstract
A memory correcting method includes steps: providing a memory with a plurality of memory bytes; respectively adding a plurality of correcting bytes to the plurality of memory bytes; providing a plurality of non-volatile compared memory bytes; detecting whether there are any underperforming bits in the plurality of memory bytes, the plurality of correcting bytes, and the plurality of compared memory bytes of the memory to complete the correction. Alternatively, the method respectively provides a plurality of compared memory address bytes for the plurality of memory bytes and for the plurality of correcting bytes for labeling underperforming-bit addresses. Then, the method detects whether there are any underperforming bits in the plurality of memory bytes, the plurality of correcting bytes, and the plurality of compared memory address bytes of the memory to complete the correction.
