Abstract: Near-memory compute elements perform memory operations and temporarily store at least a portion of address information for the memory operations in local storage. A broadcast memory command is then issued to the near-memory compute elements that causes the near-memory compute elements to perform a subsequent memory operation using their respective address information stored in the local storage. This allows a single broadcast memory command to be used to perform memory operations across multiple memory elements, such as DRAM banks, using bank-specific address information. In one implementation, the approach is used to process workloads with irregular updates to memory while consuming less command bus bandwidth than conventional approaches. Implementations include using conditional flags to selectively designate address information in local storage that is to be processed with the broadcast memory command.
