Command scheduling component for memory
Abstract:
A system includes a processing device that determines whether a memory bank is active and adds an activate command for a row of the memory bank accessed by an oldest command for the memory bank to a command scheduler in response to determining the memory bank is not active. The processing device determines whether the row of the memory bank has a corresponding row command in response to determining the memory bank is active. The processing device determines whether a close page mode is enabled or an open row timer has expired on the row and adds a precharge command to the command scheduler in response to determining the close page mode is enabled or the open row timer has expired. The processing device executes a command in the command scheduler based on a priority of commands included in the command scheduler.
