| 20080276053 | Portable Device and Method for Controlling Deep Power Down Mode of Shared Memory - The memory device may include a first determination unit for determining whether entry into a DPD mode is to be made by interpreting signals received from a first processor, and generating and outputting a corresponding first DPD entry signal; a second determination unit for determining whether entry into the DPD mode is to be made by interpreting signals received from a second processor, and generating and outputting a corresponding second DPD entry signal; and a DPD determination unit for performing control for operation in the DPD mode only when the first DPD entry signal and the second DPD entry signal are respectively received from the first determination unit and the second determination unit. In accordance with the present invention, a single piece of memory operates in the DPD mode even when a plurality of processors shares the memory, so that power consumption can be minimized. | 11-06-2008 |
