Memory module with fine-grained voltage adjustment capabilities

A method comprising:

• determining a power mode of an individual memory block within a memory module having a plurality of the memory blocks, wherein the power mode includes an active mode, a standby mode, and a deep sleep mode;
• selecting one of a plurality of voltage rails provided by a voltage generation module based on the power mode such that a voltage required to retain data in the individual memory block is minimized;
• generating a voltage selection signal based on the selected voltage rail;
• and
• applying the selected voltage rail to the individual memory block.

A non-transitory computer-readable medium having machine-readable instructions stored thereon, which when executed by a processor, cause the processor to:

• determine a power mode including an active mode, a standby mode, and a deep sleep mode of an individual memory block within a memory module having a plurality of the memory blocks;
• select one of a plurality of voltage rails provided by a voltage generation module based on the determined power mode such that a voltage required to retain data in the individual memory block is minimized;
• and
• generate a voltage selection signal based on the selected voltage rail.
