摘要： In a semiconductor memory device with multiple memory cells, each including a charge storage device and two transfer devices for transferring its charge, these memory cells are accessible with no select signal provided externally. The memory device includes a clock generator for generating first and second mutually complementary clock signals. In response to the first and second clock signals, one of first word lines and one of second word lines are activated alternately. Specifically, the first clock signal makes a memory cell accessible through a first bit line by activating the first word line and first transistor, while the second clock signal makes the memory cell accessible through a second bit line by activating the second word line and second transistor.

摘要： The semiconductor storage device of this invention includes memory cells each having two transistors and one storage capacitor. Each memory cell is connected with a first word line and a first bit line for a first port and a second word line and a second bit line for a second port. The first and second bit lines are alternately disposed in an open bit line configuration. In the operation of the semiconductor storage device, in a period when a first precharge signal for precharging each first bit line or a first sense amplifier activating signal for activating a first sense amplifier is kept in an active state, a second precharge signal for precharging each second bit line and a second sense amplifier activating signal for activating a second sense amplifier are both placed in an inactive state.

摘要： A memory array divided into a plurality of sub-memory-arrays is disposed on a chip so that, if a specified sub-memory-array is selected by a sub-memory-array selecting circuit, a normal read/write operation is performed with respect to the sub-memory-array based on an address indicated by a group of external address signals. At the same time, a clock generator for self-refresh mounted on a chip generates a word-line basic clock for self-refresh and a word-line basic clock for refresh, thereby selecting the word lines in the sub-memory-arrays which have not been selected. Prior to a predetermined time at which the sub-memory-array subjected to a refresh operation is subsequently selected, a refresh halt signal is outputted so as to forcibly halt the refresh operation, thereby preventing insufficient recharging of a memory cell. Each of the plurality of sub-memory-arrays stores, of sequential sets of image data, data on one frame or one field.

摘要： A communication device such as a video telephone is connected to a telephone line together with a telephone set at both parties. In response to an operation for removing a handset from a hook of the telephone set at this party, the video telephone at this party is initiated. Each of the video telephones includes a mode selecting switch and DTMF receiver which receives a DTMF signal from one of the telephone sets and decodes a received DTMF signal to output data representative of the mode of the video telephone. When a flag "1" is set, a mode of the video telephone at this party can be controlled in response to the DTMF signal which is received by the DTMF receiver from the telephone set at this party and, when a flat "2" is set a mode of the video telephone at this party can be controlled in response to the DTMF signal which is received by the DTMF receiver from the telephone set at the other party.
