    摘要: A semiconductor memory device having MIS transistors to constitute memory cells (MC), each of the MIS transistors including a semiconductor layer (12), a source region (15) formed in the semiconductor layer, a drain region (14) formed apart from the source region in the semiconductor layer, the semiconductor layer between the source region and the drain region serving as a channel body in a floating state, a main gate (13) provided between the source region and the drain region to form a channel in the channel body; and an auxiliary gate (20) provided separately from the main gate to control a potential of the channel body by capacitive coupling, the auxiliary gate being driven in synchronization with the main gate. The MIS transistor has a first data state in which the channel body is set at a first potential and a second data state in which the channel body is set at a second potential.

    摘要: In a removable disk storage apparatus, a reading/writing head can be stably and reliably moved so as to correspond to an information recording medium. A rotation supporting member for supporting the reading/writing head is formed of a rotary arm and an elastic supporting member fitted to a tip end portion of the rotary arm for supporting the reading/writing head. The rotary arm member is formed by bending it so that it should be dogleg-shaped. The elastic supporting body is fixed on a tip end portion of a bent portion thereof in the extended direction in which the elastic supporting body is bent. The rotary arm is inserted into a disk cartridge substantially straight with its tip end being faced to the disk cartridge, and then supported by a ramp on a center line thereof.

    摘要: A door 20 is rotatably attached to a disk cartridge 1. In mounting the disk cartridge 1, an opening and closing pin 224 moving along a groove 223 is engaged with the door 20 and the door 20 is opened. For example, when the opening and closing pin 224 cannot return to a normal standby position by some cause, a front face of the door 20 and a projected streak portion 206 are brought into contact with each other and the disk cartridge 1 cannot be inserted further. Therefore, even when the disk cartridge 1 is inserted in a state where the door 20 is not opened, there is avoided beforehand an accident where the disk cartridge 1 collides with a head, a lamp or the like to cause the destruction thereof.

    摘要: The present invention relates to a FIFO (First In First Out) memory control circuit for controlling FIFO memory which is used in various electronic devices. Specifically, the present invention relates to a FIFO memory control circuit capable of performing asynchronous read/write control hen a write clock and a read clock are different and it is known or determined which of these clocks has a higher clock frequency.
