Extensible/retractable and storable portable memory device including a main body and a sheath. The main body has an adapter at one end. One end of the sheath is formed with an opening for fitting the adapter end of the main body. The other end of the sheath is formed with a through hole through which the adapter can outward protrude. Two sides of the sheath are formed with inward projecting stop boards. The middle portions of two sides of the main body are respectively formed with two lateral projecting blocks. The stop boards stop the lateral projecting blocks from outward sliding so that the main body is restricted to relatively slide within the sheath to extend the adapter out of the sheath or retract the adapter therein and locate the adapter in a predetermined position. Therefore, the memory device can be easily used and carried.
