Abstract
A memory module includes cache of relatively fast and durable dynamic, random-access memory (DRAM) in service of a larger amount of relatively slow and wear-sensitive non-volatile memory. Local controller manages communication between the DRAM cache and non-volatile memory to accommodate disparate access granularities, reduce the requisite number of memory transactions, and minimize the flow of data external to nonvolatile memory components.
