ABSTRACT:
An error correction device includes a main memory, a memory bus coupled to the main memory, and a correction module. The correction module is coupled to the system bus and directly connected to the memory bus. The correction module reads an error data from the main memory via the memory bus according to an error address, generates a correct data according to the error data and an error value, and directly writes the correct data into the main memory via the memory bus. Because the correction module reads and writes the correct data into the main memory without using the system bus managed by an arbitrator, a number of the change row operations can be reduced to increase system efficiency.
