Systems and methods for recovering from uncorrected DRAM bit errors
Systems, methods, and computer programs are disclosed for recovering from dynamic random access memory (DRAM) defects. One method comprises determining that an uncorrected bit error has occurred for a physical codeword address associated with a dynamic random access memory (DRAM) device coupled to a system on chip (SoC). A kernel page associated with a DRAM page comprising the physical codeword address is identified as a bad page. Recovery from the uncorrected bit error is provided by rebooting a system comprising the SoC and the DRAM device. In response to the rebooting, the identified kernel page is excluded from being allocated for DRAM operation.
