ABSTRACT:
In a dynamic random access memory device, an auto-refresh method comprises receiving a command for the memory device to operate in a half-density mode. This causes a remapping circuit to remap a first memory address bit to an unused memory address location. Using the new addressing scheme, an auto-refresh operation is performed on the memory array operating in the half-density mode without skipping refresh commands.
