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.
