Publication number: 20140325311Abstract: A hybrid error correction method and a memory repair apparatus thereof are provided for a dynamic random access memory (DRAM). The memory repair apparatus includes a mode register and a hybrid error correction code and redundancy (HEAR) module. When the DRAM enters a standby mode, the mode register switches the DRAM to be controlled by the HEAR module. The HEAR module generates parity data of the error correction code within a default refresh period. The HEAR module extends the refresh period of the DRAM and uses the parity data for error detection to locate a data retention error in the DRAM until the maximum allowable refresh period supported by the HEAR module is reached. Before the DRAM returns to a working mode from a standby mode, the HEAR module performs an error correction process according to fail bit data and writes corrected data into the DRAM.Type: ApplicationFiled: July 25, 2013Publication date: October 30, 2014Applicant: Industrial Technology Research InstituteInventors: Chih-Yen Lo, Ding-Ming Kwai, Jin-Fu Li, Yun-Chao Yu, Chih-Sheng Hou
