Abstract

The utility model relates to a structure for recovering failures in data area of the memory. A tester is applied to check a plurality of memories with failures in partial data area respectively such as DDRSDARM and then the memory groups with two in each group are arranged on the front and back of a circuit board respectively, keeping one memory in each group corresponding to the other. Afterwards, according to results of previous check, eight of the connecting pins in the normally usable data area are connected in sequence to base pins on connecting ports of the circuit board. Thus, when the circuit board is arranged on the circuit board of a computer, the central processing unit can use the memory groups as normal memories, which realizes the recovery and recycle of memories with failures in partial data area, reduction in manufacturing cost and environment protection.
