A semiconductor memory device with low power consumption in driving control signals of shift registers. The device contains a plurality of memory cell arrays each composed of a predetermined number of rows of memory cells. One set of shift registers are coupled to each cell array, and the nth set of shift registers successively activate word line selection signals according to a given control signal, so that the corresponding word lines of the nth cell array will be refreshed. Also coupled to each cell array is a shift register controller. The nth shift register controller provides a control signal to the nth set of shift registers when the nth cell array is being refreshed. When the refresh of that cell array is finished, the nth shift register controller forwards the control signal to the (n+1)th set of shift registers, thus initiating refresh operation for the (n+1)th cell array.

A semiconductor memory device, in which a burst operation is performed using a memory core, has a read/write trigger signal generating circuit and a read/write signal generating circuit. The read/write trigger signal generating circuit generates a read/write signal request from a predetermined timing signal during the burst operation. The read/write signal generating circuit receives an output signal from the read/write trigger signal generating circuit and outputs a read/write signal after a core operation just prior to receipt of the output signal is complete and the subsequent activation of a row side is complete.

A method for controlling a semiconductor memory in which mode register can be set in burst mode. To set an operation mode in burst mode, the semiconductor memory is changed first from the burst mode, through power-down mode, to standby mode of non-burst mode. Then the semiconductor memory is changed to mode register set mode to set the mode register when commands are input in the same predetermined sequence that is used in the non-burst mode.

A center site is disposed to intervene in a business transaction achieved through a network. The center site includes an open business information database in which open business information received from member sites connected to the network is accumulated to be opened to the sites and a notarization database to keep therein contents of contracts of transactions between the sites. The center site receives a transaction request from a transaction partner site in accordance with the open business information and notifies the request to an information supply site associated therewith. The center site intervenes in a transaction resultantly accomplished between the information supply site and the transaction partner site and conducts a notarization process for the contents of contract for the transaction to accumulate the contract in a notarization database.
摘要:
An operation control circuit sets an inactivating timing of sense amplifiers activated in response to a read request, a write request, or a refresh request, to the timing a maximum possible quantity of signals which can be output from the sense amplifiers operating in response to the refresh request is transmitted to memory cells. Tailoring the activating period of the sense amplifiers to a refresh operation can reduce access time. A refresh control circuit generates a predetermined number of refresh requests consecutively to refresh all of the memory cells before extending the cycle of generating refresh requests. When refresh requests occur consecutively, the refresh frequency can be lowered to reduce power consumption. As a result, access time can be reduced without increasing power consumption during the standby mode.

Connections of global data buses GDB0 and GDB1 to local data buses LDB00 to LDB04 in a bank 1 are reverse to those in a bank 0. That is, the global data bus GDB0 is connected to every other local data bus LDB00, LDB02 and LDB04 including both sides in the bank 0, and to every other local data buses LDB11 and LDB13 excluding both sides in the bank 1, while the global data bus GDB1 is connected to every other local data buses LDB01 and LDB03 excluding both sides in the bank 0, and to every other local data bus LDB10, LDB12 and LDB14 including both sides. Further, bit line patterns obliquely traversing sense amplifier rows are reverse to each other with respect to the banks 0 and 1
