Abstract
Various implementations described herein relate to correcting errors in Dynamic Random Access Memory (DRAM). A memory controller uses an Error Correcting Code (ECC) to store an encoded data word within a DRAM die. The DRAM die is communicatively coupled the memory controller by a memory data bus. The DRAM die includes on-die error correction for data bits stored in the DRAM. Upon reading the encoded data word, the memory controller corrects and detects one or more errors. The one or more errors are introduced by at least one of the on-die error correction of the DRAM die or the memory data bus.
