Abstract

A memory device including a connector enabling the memory device to be coupled to a power source; a display including a bar indicator that indicates an amount of remaining storage space available in the memory device, wherein the display responds to the power source when the memory device is coupled to the power source to display information related to storage space availability on the bar indicator and continues to display such information after the memory device is uncoupled from the power source so that no power is applied to the display.

Claims

1. A memory device comprising:

a connector enabling the memory device to be coupled to a power source;

a display including a bar indicator that indicates an amount of remaining storage space available in the memory device, wherein the display responds to the power source when the memory device is coupled to the power source to display information related to storage space availability on the bar indicator and continues to display such information after the memory device is uncoupled from the power source so that no power is applied to the display.

2. A memory device as claimed in claim 1 wherein the display is removable from the memory device.

3. A memory device as claimed in claim 1 wherein the display includes memory material comprising chiral doped nematic liquid crystal.

4. A memory device as claimed in claim 1 wherein neither the memory device nor the display includes a separate power source to power the bar indicator when the memory device is uncoupled from the power source.
