    摘要: A bus driving system includes n bus wires having data signal wires and control signal wires, (n-1) switching circuits constituting driver circuits at a transmitting end, a precharge circuitry for precharging (n-2) bus wires and (n-1)-th bus wire with a control circuit for redistributing wire capacitances of transmission lines formed by the bus wires, and a predischarge circuitry for predischarging n-th bus wire. The switching circuits control conduction and non-conduction between (n-2) bus wires, (n-1)-th bus wire and n-th bus wire, wherein the (n-2) switching circuits respond to (n-2) bit signals and a control signal, while the (n-1)-th switching circuit responds to the control signal. The signal from the transmitting end is detected by a detection circuit at a receiving end via the transmission lines.

    摘要: In an LSI system using an on-chip bus, when a transfer on the bus is delayed due to a fully loaded buffer in a destination module, a source module cannot proceed to the next processing. Such an unwanted situation is eliminated by a transferring buffer which is provided on a transfer path in an on-chip bus on the LSI for temporarily storing transfer data. With this transferring buffer, even if a buffer within a slave module, specified as the destination, is fully loaded and cannot accept any more transfer, a bus master can transfer data to the transferring buffer provided on the on-chip bus. Thus, the bus master is not kept waiting for execution of a transfer, irrespective of the state of the buffer within the slave, thereby improving the processing performance of the entire system.

    摘要: A semiconductor memory device includes signal lines, a decoder for decoding an inputted address to output the decoded result to some of the signal lines, a matrixed memory array, a part of which being pre-specified as a compensated area, read out means for reading out data from memory cells in an area specified in accordance with a decode signal on the some signal line, a detector for detecting that the address is related with the compensated area from the decode signal on the some signal lines, the compensated area being pre-related with the some signal lines, and a fixed data outputting circuit for merging predetermined data into a predetermined part of the data read out from the memory cells in accordance with the detection signal to output the merged data. The fixed data outputting circuit is controlled by a control circuit in response to a merge control signal to output the data read out from the memory cells without the merging operation.
