Claim Text:
1. A method for recovering from dynamic random access memory (DRAM) defects executed by instructions embodied on a non-transitory computer readable medium, the method comprising: 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); in response to the determination of an uncorrected bit error, branching an operating system to an exception handler running at least one recovery module from one of a static random access memory (SRAM) device and a read only memory (ROM) located on the SoC; determining with the recovery module whether a bit failure occurred at the DRAM device as a result of an error correction code (ECC) error; and responsive to the determination whether the bit failure occurred as a result of ECC error:
