摘要:
Methods and apparatus for closed-case removable expansion cards having a removable memory enhance the utility of portable computer hosts, such as PDAs. In both a first and second embodiments the closed-case removable expansion cards preferably use a Type II CompactFlash form factor. In the first embodiment the removable memory is in combination with an external-I/O connector or attached external-I/O device, providing both I/O and memory functions in a single closed-case removable expansion card. This increases the expansion functional density for portable computer hosts, such as PDAs. That is, it increases the amount of functionality that can be accommodated within a given volume allocation for expansion devices. In the second embodiment the removable memory is a private memory for application specific circuitry within the closed-case-removable expansion card. This enhances the utility of portable computer hosts, such as PDAs, as universal chassises for application specific uses. The standard CompactFlash physical and electrical interface couples the application specific card to the host, which provides user interface functions for the application. The cards include a top located slot and an internal connector for accepting a MultiMediaCard as the private removable memory. In addition, the application specific card will generally have some manner of I/O to required external devices, such as scanning devices, sensors, or transducers. Otherwise, all functionality for the application specific function is self-contained within the application specific card.
