Patent ID: 7225289

Claim:
A virtual integrated drive electronics (IDE) storage device with a peripheral component interconnect (PCI) Express interface, comprising: a microcontroller, having a flash memory interface and a PCI Express interface capable of converting a data into a flash memory format or a PCI Express format, and a virtual IDE module capable of receiving an instruction given by a host, and said virtual IDE module having an IDE host for receiving an IDE instruction given by said host and an IDE device for completing execution of said IDE instruction; a flash memory, coupled to said microcontroller for storing or reading data; a PCI Express connecting interface, configured for connecting to a PCI Express bus disposed in said host, and provided for coupling said microcontroller to said host, such that when said host stores or reads a data of a flash memory, said microcontroller of said storage device will declare to said host that said storage device is an IDE host, and said IDE instruction given by said host will be sent to said virtual IDE module and the execution of said instruction will be completed by said virtual IDE module, and said data in said flash memory will follow said instruction, and said data will be converted by said flash memory interface and said PCI Express interface of said microcontroller into a data format acceptable by said flash memory or said PCI Express bus, and then said data will be sent to said host or stored in said flash memory.
