Abstract: A PCI(Peripheral Component Interconnect) target controller having design versatility is provided to enable a user to adjust a memory size free by putting a prefetch memory to the outside to have a more improved configuration than a PCI2.2 structure, and offer a hardware structure attaching no memory in case that an application supports only the instant transmission. The PCI target controller includes a signal line for a PCI interface, the signal for a local interface, an EEPROM(Electronically Erasable Programmable ROM) interface signal line, a memory interface signal line, a buffer block, a PCI interface control unit, a local interface control unit, PCI interface state machines, a data size counter, and a configuration register control block. The EEPROM interface signal line makes information of an EEPROM(50) set to an internal register of a target controller(C) in a system initialization process. The memory interface signal line stores the prefetch data to a dual port memory(M). The PCI/local interface control unit generates and detects a signal of the PCI interface and the local interface.
