摘要： A synchronous DRAM has cell arrays arranged in matrix, divided into banks accessed asynchronously, and n bit I/O buses for transferring data among the cell arrays. In the DRAM, the banks are divided into m blocks, the n-bit I/O buses located between adjacent banks, is used for time sharing between adjacent banks in common, the n bit I/O buses, used for time sharing between adjacent banks in common, are grouped into n/m-bit I/O buses, every n/m bits for each block of m blocks of bank, and in each block in each bank, data input/output are carried out between the n/m-bit I/O buses and data bus lines in each block. A synchronous DRAM includes a first and second internal clock systems for controlling a burst data transfer in which a string of burst data being transferred in synchronism with an external clock signal, when one of the internal clock systems is driven, the burst data transfer is commenced immediately by the selected internal clock system.

摘要： A flip-flop circuit for driving an input circuit of a synchronous dynamic random access memory (SDRAM) comprised of a complementary pair of data inputs for receiving data pulses, a clock input for receiving clock pulses, a capture latch circuit for capturing a bit, having a pair of complementary inputs and a pair of complementary outputs, apparatus for applying data pulses from the complementary data inputs to the inputs of the capture latch, apparatus for triggering the capture latch from the clock pulses, and apparatus for connecting the complementary outputs to each other through a bidirectional holding latch, whereby during coincidence of a rising edge of a clock pulse and the presence of a data pulse of one polarity, the capture latch is enabled to store a bit corresponding to the data pulse, and to drive the pair of complementary outputs, and following the leading edge of a clock pulse and the one polarity of the data pulse the complementary outputs remain driven by the holding latch.

摘要： A semiconductor memory device including a serial I/O buffer (19); DRAM cells (1); and SAM cells (4,5) arranged in line, the SAM cells corresponding to the DRAM cells in one row. In the device in a first mode, the SAM cells (4,5) are divided into N first portions each having boundaries, data stored in the SAM cells being transferred to the serial I/O buffer (19) sequentially until the SAM cells in the boundaries of the first portions are transferred to the serial I/O buffer. In a second mode, the SAM cells (4,5) are divided into M (N>M) second portions each having boundaries, data stored in the SAM cells being transferred to the serial I/O buffer (19) sequentially until the SAM cells in the boundaries of the second portions are transferred to the serial input output buffer. The semiconductor memory device further includes a circuit for detecting changes from the first mode to the second mode and from the second mode to the first mode. The semiconductor memory device further includes a circuit for generating a first and a second signals. When a mode is changed from the first mode to the second mode, the circuit generates the first signal. When the mode is changed from the second mode to the first mode the circuit generates the second signal.

摘要： The present invention includes a memory subsystem comprising at least two semiconductor devices (15, 16, 17), including at least one memory device (15, 16 or 17), connected to a bus (18), where the bus includes a plurality of bus lines for carrying substantially all address, data and control information needed by said memory devices (15, 16 or 17), where the control information includes device-select information and the bus (18) has substantially fewer bus lines than the number of bits in a single address, and the bus (18) carries device-select information without the need for separated device-select lines connected directly to individual devices. The present invention also includes a protocol for master and slave devices to communicate on the bus (18) and for registers in each device to differentiate each device and allow bus requests to be directed to a single or to all devices (15, 16, 17). The present invention includes modifications to prior-art devices to allow them to implement the new features of this invention. In a preferred implementation, 8 bus data lines and an Address Valid bus line carry address, data and control information for memory addresses up to 40 bits wide.

摘要： An upper column address strobe signal CAS U ¯ and a lower column address strobe signal CAS L ¯ applied to a dynamic RAM 100 are 180° out of phase from each other. Data of n bits are read out from a memory cell array 105 at a time. The data read out from memory cell array 105 is divided into two bit groups and applied to an upper IO buffer 107 and a lower IO buffer 108. Upper IO buffer 107 and lower IO buffer 108 latch sequentially the upper bit group and the lower bit group and output these groups to a data transmission bus 2 in response to the upper column address strobe signal CAS U ¯ and the lower column address strobe signal CAS L ¯ .

摘要： A synchronous dynamic random access memory device allows an external device to sequentially access read-out data bits in synchronous with a system clock signal (CK), and a column addressing system (151) incorporated in the synchronous dynamic random access memory device forms a plurality of pipeline stages (150c/150d; 150e; DFF4/DFF5) together with an input/ output unit (161) for sequentially supplying data bits to a data port (DP10) in response to a column address (DC1) internally incremented in synchronism with the system clock signal, thereby propagating the data bits through a single data bus (161a).
