Abstract: PROBLEM TO BE SOLVED: To prevent a current to be consumed from flowing to a memory cell not selected, by connecting a pair of switches between a pair of bit lines writing and reading with respect to memory cells and each memory cell, and connecting memory cells selectively to the bit lines. SOLUTION: An AND path gate is constituted at each memory cell arranged on a pair of bit lines B, BB with the use of two pairs of selecting switches (path gate transistors Q1, Q2 having gate inputs through word lines X1, X2,...Xm and path gate transistors Q1', Q2' having gate inputs through bit lines Y1, Y2,...Yn). Even when one pair of bit lines B, BB is selected by a column decoder and started to be precharged and equalized, only the memory cell selected by the bit line Y and work line X is activated, and a consumption current does not flow to the other memory cells connected to the same word line. One pair of bit lines is shared among adjacent memory cells in a direction of the word line, so that a count of bit lines is reduced.

Abstract: PURPOSE: To form a system for transmitting the stored program of movie or music through the distribution network(DN) of cable television or the like to a client. CONSTITUTION: Concerning this system, the program is compressed and stored in a program library(PL) 102. When a request to the program is received, a request processor(RP) 101 transmits a control message(CM) 104, reads a data block(DB) having the requested program out of the PL 102 and stores it in a DRAM inside a server. The server transmits the program from the DRAM through a distribution system to the client as series of digital packets. The transmission of program is managed by another command word(CW). The client can operate such as fast forward by transmitting the CM for changing a pointer in the CW. In order to simultaneously transmit audio and/or video overlay, the CW is divided into groups and linked for transmitting a program sequence. Interfaces to the RP 101, PL 102 and DN can be arranged at different positions.

Abstract: PURPOSE:To improve the handleability of functions by changing correspondent temporary registration call source information into the information of a holding reception destination when a call is originated by using a super bell signal. CONSTITUTION:A registration table is provided with a storage part 15 for utilizing a super bell function, and a control part (central controller CC) 14 executes the service function based upon the contents of this table. When the super bell call is originated by holding a received call after that call is responded, the responding party is connected to a line wire during holding. Then, the telephone can be performed directly between both of them and the super bell function can be utilized. In this case, the control part 14 temporarily stores the information of a terminal T0 in a super bell call requesting source storage table as the call requesting source information corresponding to the super bell. Thus, when a user received a call while designating the super bell number from the terminal, the handleability of the function can be improved since the call requesting source can be recognized.
