摘要： A push-pull type output circuit is used in the differential amplifier of a voltage converter circuit. The threshold voltage of the driving transistor is set lower than the voltages of the transistors of the other circuits to operate the differential amplifier at a voltage higher than the power supply voltage. By using the push-pull type output circuit, the amplitude increases and it is possible to raise the capacity of the driving transistor. Moreover, by setting the threshold voltage of the driving transistor of the buffering circuit lower than the threshold voltages of the transistors of the other circuits, it is possible to further raise the driving capacity. Increase of the sub-threshold current due to lowering of the threshold voltage can be prevented by operating the differential amplifier at a voltage higher than the power supply voltage.

摘要： A memory system is provided which is capable of eliminating deterioration in a processing rate due to possible signal delays between an input/output circuit and memory blocks. Complication of design is also reduced, especially when the scale and chip area of the memory system increase. A memory chip includes a plurality of memory array blocks each including an address buffer and an address counter, and operates on the basis of a local clock cycle. A control circuit is synchronous with a clock of an external device, and synchronous data-transfer circuitry includes a buffer which modulates the transfer rate of serial data which arrives from a memory array block at a local clock cycle so as to be synchronous with the clock of the control circuit. External clock signal lines are not distributed to the memory array blocks.

摘要： In a semiconductor memory, switch circuits are provided so as to inhibit voltage and signal supplies to each of the normal memory blocks when so required. On the other hand, a ROM is provided on the chip so as to store the address of a defective memory block which consumes an excessively large stand-by current when the semiconductor memory is in the stand-by mode. The switch circuits are controlled by the output of the ROM so as to inhibit the voltage and signal supply to the defective memory block. Then, a spare memory block which is substituted for the defective normal memory block receives the voltage and signal supply.

A device for supporting the second lens group is supported by a device for supporting the first lens group in such a manner that the second lens group supporting device is movable along the optical axis relative to the first lens group supporting device. When a drive ring for driving the first lens group supporting device is activated, the first lens group supporting device is moved forward or rearward along the optical axis in response to the rotation of the drive ring and, at the same time, a drive cam device for driving the second lens group supporting device to move along the optical axis relative to the first lens group supporting device is caused to rotate around the optical axis by the drive ring.
