Abstract
A method of ECC encoding a DRAM and a DRAM thereof. The method comprises determining whether to encode the data according to the value of a flag bit while the DRAM is being refreshed. The ECC encoding module encodes data only if of the flag bit setting and detecting module generates an enable signal. As a result, the length of the valid data for ECC encoding can be guaranteed to comply with the requirements of ECC encoding.
