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.

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.

A cache memory including a first memory array and a main memory including a second memory array are integrated together on the same semiconductor substrate. Each memory cell in the first memory array is of a 2Tr1C type including: first and second transistors, the sources of which are connected together; and a data storage capacitor, one of the two electrodes of which is connected to the common source of the first and second transistors. Each memory cell in the second memory array is of a 1Tr1C type including: a third transistor; and a data storage capacitor, one of the two electrodes of which is connected to the source of the third transistor.

An electromagnetic induction device which comprises a split-type core assembly comprising at least one winding formed thereon and first and second core segments each having at least two joint faces spaced apart from each other, the first and second core segments are connected together with the joint faces of one of the first and second core segments held in contact with the joint faces of the other of the first and second core segments, and a finely divided ferromagnetic material is interposed between the joint faces of the respective first and second core segments. The ferromagnetic material used has an average particle size sufficient to form a magnetic fluid medium.
