Approach for managing near-memory processing commands and non-near-memory processing commands in a memory controller

Abstract

An approach is provided for managing PIM commands and non-PIM commands at a memory controller. A memory controller enqueues PIM commands and non-PIM commands and selects the next command to process based upon various selection criteria. The memory controller maintains and uses a page table to properly configure memory elements, such as banks in a memory module, for the next memory command, whether a PIM command or a non-PIM command. The page table tracks the status of memory elements as of the most recent memory command that was issued. The page table includes an 'All Bank' entry that indicates the status of banks after processing the most recent PIM command. For example, the All Banks entry indicates whether all the banks have a row open and if so, specifies the open row for all the banks.
