Abstract
A portable memory device having a flexible polymeric display panel which comprises a memory controller configured to determine memory information from a memory coupled to the memory controller, generate memory information signals in dependence on the determined memory information and output the memory information signals to a display driver. The display driver is configured to convert the memory information signals into visual representation signals. The visual representation signals are then outputted on the flexible polymeric display panel. In one embodiment, a secure digital (SD) flash memory card has an electrophoretic display on the card housing and the display indicates information such as the amount of storage available in the card.
Claims31
A portable memory device comprising:
- a housing that conforms to a portable memory device form factor;
- a memory controller in the housing and configured to determine memory information from a memory coupled to the memory controller, generate memory information signals in dependence on the determined memory information and output the memory information signals;
- a flexible polymeric display panel on the housing;
- a display driver in the housing and operatively coupled to the memory controller and configured to convert the memory information signals into visual representation signals and output the visual representation signals to the flexible polymeric display panel.
A portable memory device having a flexible polymeric display panel comprising:
- means for determining memory information from a memory associated with the portable memory device;
- means for generating memory information signals in dependence on the determined memory information;
- means for converting the memory information signals into visual representation signals;
- and,
- means for outputting the visual representation signals on the flexible polymeric display panel.
A memory device comprising:
- a memory controller configured to determine memory information from a memory coupled to the memory controller, generate memory information signals in dependence on the determined memory information and output the memory information signals;
- a flexible electrophoretic display panel;
- a display driver operatively coupled to the memory controller and coupled to the flexible electrophoretic display panel and configured to convert the memory information signals into visual representation signals and output the visual representation signals on the electrophoretic display panel;
- and
- a Secure Digital (SD) memory card housing that contains the memory controller, the memory, the display driver and the flexible electrophoretic display panel.
A memory device comprising:
- a memory controller configured to determine memory information from a memory coupled to the memory controller, generate memory information signals in dependence on the determined memory information and output the memory information signals;
- a flexible electrophoretic display panel;
- an interface coupled to an external system and configured to receive a waveform from the external system having voltage levels configured to drive the flexible electrophoretic display panel and to convert the memory information signals into visual representation signals and output the visual representation signals on the electrophoretic display panel;
- and,
- a memory card housing that contains the memory controller, the memory, and the interface, wherein the flexible electrophoretic display panel is on the housing.
