Systems and methods for recovering from uncorrected DRAM bit errors
Abstract:
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.
