摘要： A memory system of a high-speed operation can be realized by reducing an influence of reflection signals etc. caused by branching and impedance mismatching in various wirings between a memory controller and a memory module, and an influence due to transmission delays of data, command/address, and clocks in the memory module. To this end, a memory system comprises a memory controller and a memory module mounted with DRAMs. A buffer is mounted on the memory module. The buffer and the memory controller are connected to each other via data wiring, command/address wiring, and clock wiring. The DRAMs and the buffer on the memory module are connected to each other via internal data wiring, internal command/address wiring, and internal cock wiring. The data wiring, the command/address wiring, and the clock wiring may be connected to buffers of other memory modules in cascade. Between the DRAMs and the buffer on the memory module, high-speed data transmission is implemented using data phase signals synchronous with clocks.

摘要： A semiconductor device includes a stacked plurality of memory chips. The memory chips each include a plurality of memory banks, a plurality of read/write buses that are assigned to the respective memory banks, and a plurality of penetration electrodes that are assigned to the respective read/write buses and arranged through the memory chip. Penetration electrodes arranged in the same positions as seen in a stacking direction are connected in common between the chips. In response to an access request, the memory chips activate the memory banks that are arranged in respective different positions as seen in the stacking direction, whereby data is simultaneously input/output via the penetration electrodes that lie in different planar positions.

摘要： To decrease the circuit scale necessary for the calibration of the output circuit and to decrease the time required for the calibration operation. The invention includes a first output buffer and a second output buffer that are connected to a data pin, and a calibration circuit that is connected to a calibration pin. The first output buffer and the second output buffer include plural unit buffers. The unit buffers have mutually the same circuit structures. With this arrangement, the impedances of the first output buffer and the second output buffer can be set in common, based on the calibration operation using the calibration circuit. Consequently, both the circuit scale necessary for the calibration operation and the time required for the calibration operation can be decreased.

摘要： Disclosed herein is a semiconductor device that includes an access control circuit generating an internal command based on a verification result signal and an external command. The external command indicates at least one of a first command that enables the access control circuit to access a first circuit and a second command that enables the access control circuit not to access the first circuit or enables the access control circuit to maintain a current state of the first circuit. The access control circuit, when the verification result signal indicates a first logic level, generates the internal command based on the external command. The access control circuit, when the verification result signal indicates a second logic level, generates the internal command that corresponds to a second command even if the external command indicates a first command.
