Abstract

A storage memory device includes a primary body comprised of a first memory card at one side and a connection portion at the other side. Contacts are provided in the connection portion and in electrical connection with the first memory card to serve as a data transmission interface for the first memory card. The storage memory device further includes a secondary body forming a first slot for receiving the connection portion therein. The secondary body may include a second memory card electrically connectable to the first memory card via the contacts of the connection portion. Alternatively, the second memory card of the secondary body is omitted and replaced by a second slot into which another primary body comprised of a connection portion having contacts and a memory card is received. Thus, electrical connection and data exchange between the two memory cards, either between the first and second memory cards or between the two first memory cards, can be done easily with the contacts of the connection portions.

Claims

1. A storage memory device comprising:

a primary body including a first memory card at one side and an extended connection portion at the other side, said extended connection portion having two sides each being formed with a notch; and

a secondary body having a first slot for receiving said extended connection portion, and a pair of snap-on arms formed on two sides of said first slot, each snap-on arm having a barb for engaging with said notch;

wherein at least one contact in electrical connection with said first memory card is formed on said extended connection portion for forming a transmission interface for said first memory card.

2. The storage memory device as claimed in claim 1, wherein said primary body further has two recessed edges and said secondary body has two extended side arms for coupling with said two recessed edges.

3. The storage memory device as claimed in claim 1, wherein said extended connection portion is configured to be compatible with USB connection.

4. The storage memory device as claimed in claim 1, wherein said secondary body further comprises a second memory card that is electrically connectable to said first memory card by means of said at least one contact of said extended connection portion.

5. The storage memory device as claimed in claim 1, wherein said secondary body further comprises a second slot formed on an opposite side of said first slot, and a pair of snap-on arms formed on two sides of said second slot, said second slot having a configuration substantially identical to said first slot for receiving a memory body having a configuration substantially identical to said primary body.
