A bad page management system is provided to guarantee a yield of a volatile semiconductor memory device such as a DRAM. A bad page list exists in a DRAM. A page remapper in a memory controller performs a page remapping operation in parallel with a normal operation of a scheduling unit to perform a latency overhead hidden function. A chip size of the DRAM is reduced or minimized. A DRAM controller performs a latency overhead hidden function to control a DRAM.

A system on chip (SOC) includes a slave device, a plurality of master devices, an interconnect device and a plurality of service controllers. The master devices generate requests to demand services from the slave device. The interconnect device is coupled to the slave device and the master devices through respective channels, and the interconnect device performs an arbitrating operation on the requests. The service controllers control request flows from the master devices adaptively depending on an operational environment change of the SOC.

In a semiconductor memory device and an internal data transmission method thereof, the device includes a memory controller, a pair of data lines, and a plurality of memory banks. During an internal data transmission operation, the memory controller externally receives and stores a source address and a target address in response to an externally applied command and outputs an internal control signal and an internal address signal using the source address and the target address. The internal control signal includes an internal write signal and an internal read signal. Transmission data is transmitted on the pair of data lines during the internal data transmission operation. The plurality of memory banks read the transmission data stored in a region corresponding to the source address in response to the internal read signal, transmit the transmission data on the pair of data lines, and write the transmission data transmitted on the pair of data lines in response to the internal write signal. During the internal data transmission operation, the transmission data is transmitted from the region corresponding to the source address to a region corresponding to the target address, and is not output external to the semiconductor memory device

The magnetic head of the present invention comprises a recording head section having a first gap of a given width and a reading/erasing head section having a second gap. The middle portion of the second gap is straight by the given width, and parallel with the gap of the recording head section. Both side portions of the second gap are symmetrically bent at an angle towards the recording head section so that the magnetic head can prevent the data error while reading information from a diskette.

A system comprising a processor is programmed to receive vehicle data from a plurality of vehicles, user data of customers and user data of promoters who are offering his vehicle for test drive. The system allows the customers to find vehicles available for test drive based on a search query generated using the user data that includes the customer's driving profile. The test drive vehicles matching the search query is identified based on the vehicle data of the vehicles, in which at least some of the usage profile of the vehicle is originated from the vehicle computer, telematics system or sensors provided in the vehicle. The promoters availing his own vehicle for test drive by customers are rewarded upon verification of a successful completion of a test drive event.
