U.S. patent application Ser. No. 11/771,744, entitled “Method of Using The Dual Bus Interface In An ExpressCard Slot,” by Jonathan Hubert, et al., filed on even date herewith, now U.S. Publication No. 2009/0006707.
A few years ago, a coalition of member companies of the Personal Computer Memory Card International Association (PCMCIA) developed the ExpressCard® peripheral as a new standard for PC Card technology. FIG. 1 shows a pair of ExpressCard memory cards 20 and 22 according to the two standard ExpressCard form factors. ExpressCard module 20 has a length of 75 mm and a largest width of 54 mm. ExpressCard module 22 has a length of 75 mm and a width of 34 mm. Both formats are 5 mm thick.
Due to space and cost constraints, host computing platforms 30 typically only include a single ExpressCard slot. In platforms having only a single ExpressCard slot, when an ExpressCard module 20/22 is inserted into the slot, the slot is then no longer available to perform any other functions. This is so despite the fact that the interface has two independent buses—the high performance PCIe bus and the more common USB interface. At present, there are no known peripheral devices that leverage both buses within the same ExpressCard slot.
As seen in FIG. 2 and the view along line 3-3 seen in FIG. 3, a front of the peripheral device 100 includes a front interface 110 including female electrical connectors for mating with pins within a standard ExpressCard slot. As used herein, the “front” of the peripheral device refers to the portion of the device inserted first into the ExpressCard slot and located at the rear of the slot when inserted; the “back” of the peripheral device refers to the portion of the device located at the front opening of the slot when the device is inserted. In embodiments, interface 110 will be configured to mate with the standard, 26 pin, beam-on blade style connector used in the ExpressCard slot. As explained hereinafter, it is contemplated that the peripheral device 100 may be used in other types of card slots which may include other types of interface connectors at a front of the adapter in alternative embodiments.
A fourth function of side rails 116 a and 116 b is to defeat the ejector mechanisms conventionally provided in all ExpressCard slots. In particular, it is known to provide conventional ejector mechanisms within an ExpressCard slot for ejecting memory cards. Such ejector mechanisms include a pushbutton ejector commonly used in older PC Card slots and a so-called “push-push” mechanism where pushing on a back end of a module may secure a module within the ExpressCard slot and, once secured, pushing on the back end of the module again may eject the module from the slot. The functions of ejector mechanisms may be incompatible with a peripheral device according to embodiments of the present invention. In particular, a user may wish to position embodiments of peripheral device 100 within the ExpressCard slot, and leave it there while inserting and removing memory modules which operate with peripheral device 100 (as explained hereinafter). Pushing an ejector button or a memory card within the push-push ejector slot may eject not only the memory card but, inconveniently, the peripheral device 100 as well.
Accordingly, embodiments of the present invention provide “set-it-and-forget-it” functionality to peripheral device 100. That is, a user may insert peripheral device 100 into an ExpressCard slot, and thereafter the user may insert and remove memory cards without any additional actions or attention required by the user to peripheral device 100. This functionality is provided by side rails 116 a, 116 b, which are configured to disable (i.e., render ineffective) ejector mechanisms provided within an ExpressCard slot.
Referring now to FIG. 7, there is shown a high level block diagram of peripheral device 100 coupled via the ExpressCard interface to a host computing platform 134. As seen in FIG. 7, the interior peripheral device 100 includes an integrated memory module 140 capable of transferring data to and from host computing platform 134 via the PCIe bus interface of the ExpressCard slot. The interior of peripheral device 100 further includes a reader 142 capable of receiving memory card 120. The reader 142 is capable of transferring data between the host computing platform 134 and card 120 via the USB bus interface of the ExpressCard slot. As used herein, the term “memory module” may refer to an integrated semiconductor memory, as in the case of module 140, or a portable semiconductor memory, as in the case of memory card 120. Memory card 120 may be any of various known memory card standards having a size capable of fitting within the reader 142.
In the embodiments of FIGS. 9-13, peripheral device 100 includes a memory module assembly 150 and a memory card 130. Memory module assembly 150 may be identical to the adapter assembly 100 disclosed in U.S. patent application Ser. No. 11/771,767 entitled “Adapter for an ExpressCard Slot” (previously incorporated by reference) with one exception. Namely, adapter assembly 100 in the incorporated application includes an adapter 102 which is simply a pass-through of electrical leads connecting the front and back interfaces. In the embodiments of FIGS. 9-13 of the present invention, the adapter 102 of the incorporated application is replaced with a memory module 152 similar in operation to memory module 140 described above. Memory module 152 may include a front interface 154 similar to interface 110 described above, and side rails 156 a and 156 b similar in function to side rails 116 a and 116 b described above. Memory module 152 may be 45 mm in length, 34 mm in width and 5 mm high to thus fit snugly within the back end of the ExpressCard slot.
The present invention discloses an embodiment where memory card 130 operates together with memory module 152 to utilize the two buses of the ExpressCard slot. In such an instance, memory card 130 uses the USB interface. However, it is also contemplated that memory card 130 can operate within ExpressCard slot 160 without memory module 152. In particular, memory card 130 may operate with an adapter assembly 200 (FIGS. 14-15), which may be the same as the adapter assembly 100 disclosed in the previously incorporated patent application entitled “Adapter for an ExpressCard Slot.”
FIG. 14 shows a first adapter, adapter assembly 200. Adapter assembly 200 is the same as the adapter assembly 100 disclosed in the above-referenced Adapter patent application. Instead of adapter assembly 200, a memory module assembly 150 as described above may be used. The figures indicate this with reference numbers “150/200,” indicating that the assembly shown may either be a memory module assembly 150 or an adapter assembly 200. FIG. 14 further shows a second adapter, adapter 180. Adapter 180 may have the same form factor and external features as memory card 130. Namely, adapter 180 may have a length of approximately 45 mm, a width of approximately 34 mm and a height of approximately 4 mm.
Adapter 180 may include a front interface 182 capable of mating with a back interface on memory module assembly 150/adapter assembly 200 (hereinafter “assembly 150/200”. Adapter 180 may further include a slot 184 for receiving a memory card, such as memory card 120 described above. A lip 184 may also be provided on adapter 180. Lip 184 functions similar to lip 132 in the above-referenced Adapter patent application to prevent adapter 180 from getting lost within the ExpressCard slot 160 in the absence of adapter 200.
