Controlling a refresh mode of a dynamic random access memory (DRAM) die

A dynamic random-access memory (DRAM) system, comprising:

• means for configuring an inactive portion of a DRAM die to operate in accordance with a self-refresh mode that is characterized by refreshes of the DRAM die being controlled by a local DRAM die controller integrated into the DRAM die;
• and
• means for configuring an active portion of the DRAM die to operate in accordance with a controller-managed refresh mode while the inactive portion of the DRAM die operates in the self-refresh mode, the controller-managed refresh mode characterized by refreshes of the DRAM die being controlled by a controller that is external to the DRAM die.

A non-transitory computer-readable medium containing instructions stored thereon, which, when executed by a dynamic random-access memory (DRAM) system, cause the DRAM system to perform operations, the instructions comprising:

• at least one instruction to cause the DRAM system to configure an inactive portion of a DRAM die to operate in accordance with a self-refresh mode that is characterized by refreshes of the DRAM die being controlled by a local DRAM die controller integrated into the DRAM die;
• and
• at least one instruction to cause the DRAM system to configure an active portion of the DRAM die to operate in accordance with a controller-managed refresh mode while the inactive portion of the DRAM die operates in the self-refresh mode, the controller-managed refresh mode characterized by refreshes of the DRAM die being controlled by a controller that is external to the DRAM die.
