Abstract
An improved compact flash memory card system includes an improved compact flash memory card desktop adapter and an improved compact flash memory card. The improved compact flash memory card desktop adapter utilizes a fifty pin socket to interface with the compact flash memory card. The desktop adapter also utilizes a plug adapter to interface with a computer. For more efficient communication between the improved compact flash memory card and the computer, the improved desktop adapter adopts the universal serial bus architecture. The improved compact flash memory card utilizes a fifty pin connection to interface with a computer through an interface device. The fifty pin connection of the flash memory card can be used with different interface devices in a variety of configurations such as a universal serial bus mode, PCMCIA mode, and ATA IDE mode. Each of these modes of operation require different protocols. Upon initialization with an interface device, this improved compact flash memory card automatically detects which operation mode is used by this interface device and configures the memory card to be compatible with the present operation mode. Because all fifty pins of the flash memory card are occupied to either transfer data or provide control signals to and from the flash memory card, this improved flash memory card merely senses selected pins to determine the present mode of operation.
