Abstract

A storage device includes a base board and a memory chip package. The base board includes, on a first edge, a connector that is connectable to a host device and through which the storage device communicates with the host device, on a second edge that is opposite to the first edge, a first engaging portion by which the base board is fixable to the host device, and in an intermediate portion that is located between the first edge and the second edge, a second engaging portion by which the base board is fixable to the host device when an end portion of the base board between the second edge and the intermediate portion is removed. The memory chip package is disposed on a surface of the base board and between the first edge and the intermediate portion.

First claim

What is claimed is:

1. A storage device, comprising:
a base board including
on a first edge, a connector that is connectable to a host device and through which the storage device communicates with the host device,
on a second edge that is opposite to the first edge, a first engaging portion by which the base board is fixable to the host device, and
in an intermediate portion that is located between the first edge and the second edge, a second engaging portion by which the base board is fixable to the host device when an end portion of the base board between the second edge and the intermediate portion is removed; and

a memory chip package disposed on a surface of the base board and between the first edge and the intermediate portion.

2. The storage device according to claim 1 , wherein
the base board includes a ground layer therein, and
each of the first and second engaging portions has a terminal that is electrically connected to the ground layer.

3. The storage device according to claim 2 , wherein
a coverage of the ground layer in the base board is greater than a coverage of the terminals in the base board.

4. The storage device according to claim 1 , wherein
the first engaging portion includes a semicircular recess, and
the second engaging portion includes a semicircular hole formed so as to become a semicircular recess when the portion of the base board is removed.

5. The storage device according to claim 1 , wherein
each of the first and second engaging portions includes a circular hole.

6. The storage device according to claim 1 , wherein
the base board further includes a fragile portion that is positioned between the intermediate portion and the end portion and extends in a direction parallel to the second edge.

7. The storage device according to claim 6 , wherein
the fragile portion includes a recess or hole that extends in the direction parallel to the second edge.

8. The storage device according to claim 6 , wherein
the fragile portion includes a plurality of holes arranged along the direction parallel to the second edge.

9. The storage device according to claim 1 , wherein
the base board further includes, in a second intermediate portion that is located between the first edge and the intermediate portion, a third engaging portion by which the base board is fixable to the host device when an end portion of the base board between the second edge and the second intermediate portion is removed, and
the memory chip package is disposed between the first edge and the second intermediate portion.

10. The storage device according to claim 9 , wherein
the base board further includes a second fragile portion that is positioned between the second intermediate portion and the intermediate portion and extends in a direction parallel to the second edge.

11. A computing device, comprising:
a circuit board having a receptor; and
a storage device disposed on the circuit board, the storage device including:
a base board including
on a first edge, a connector that is connected to the receptor and through which the storage device communicates with the circuit board,
on a second edge that is opposite to the first edge, an engaging portion that is fixed to the circuit board, and
in an intermediate portion that is located between the first edge and the second edge, a remnant engaging portion that is not fixed to the circuit board and structured substantially similarly to the engaging portion; and

a memory chip package disposed on a surface of the base board and between the first edge and the intermediate portion.

12. The computing device according to claim 11 , wherein
the base board includes a ground layer therein, and
each of the engaging portion and the remnant engaging portion has a terminal that is electrically connected to the ground layer.

13. The computing device according to claim 12 , wherein
a coverage of the ground layer in the base board is greater than a coverage of the terminals in the base board.

14. The computing device according to claim 11 , wherein
the engaging portion includes a semicircular recess, and
the remnant engaging portion includes a semicircular hole.

15. The computing device according to claim 11 , wherein
the base board further includes a fragile portion that is positioned between the intermediate portion and the end portion and extends in a direction parallel to the second edge.

16. A method for connecting a storage device to a host device thereof, the storage device having:
a base board including
on a first edge, a connector that is connectable to a host device and through which the storage device communicates with the host device,
on a second edge that is opposite to the first edge, a first engaging portion, and
in an intermediate portion that is located between the first edge and the second edge, a second engaging portion; and

a memory chip package disposed on a surface of the base board and between the first edge and the intermediate portion, the method comprising:
removing an end portion of the base board between the second edge and the intermediate portion, such that the second engaging portion is located on a removed edge of the base board;
connecting the base board from which the end portion has been removed, to a receptor of the host device that is disposed on a circuit board, such that the storage device can communicate with the host device; and
fixing the base board to the circuit board through the second engaging portion.

17. The method according to claim 16 , wherein
the base board is fixed to the circuit board at the second engaging portion using a fixing member.

18. The method according to claim 17 , wherein
the fixing member is formed of an electrically-conductive material, and the base board at the second engaging portion is electrically connected to ground by being fixed by the fixing member.

19. The method according to claim 16 , wherein
the base board further includes a fragile portion that is positioned between the intermediate portion and the end portion and extends in a direction parallel to the second edge, and
the end portion is removed by dividing the base board along the fragile portion.

20. The method according to claim 19 , wherein
the fragile portion includes a recess or hole that extends in the direction parallel to the second edge.
