Title: Semiconductor memory
Inventor: KOYOU KAZUTO
IPC: G11C11/407
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To reduce a supply current and to reduce power consumption by sharing a transistor for clock selection signal input in plural word recording parts to decrease the number of transistors to be driven by a clock selection signal. SOLUTION: When a clock selection signal CLKSEL becomes a low level, a transistor MP100 is turned ON. At this time, when an address selection signal ADDSEL-1 becomes a high level, the transistor MP200 of a word recording part 710-1 is turned ON and the transistor MN200 of the part is turned OFF. Consequently, a node N100 becomes a high level and the level is amplified in transistors MP300, MN300 and MP400, MN400 consisting of an inverter to make a word line WD1 a high level to be selected. At this time, word lines WD2-32 become low levels. Thus, charging and discharging currents are reduced and a selection speed is made high-speed by decreasing the number of transistors while sharing the transistor for clock selection signal input in such a manner.

Title: Low-noise oscillator
Inventor: ASAKA TAKAO
IPC: H03B5/32
Filed: 1986-09-29
Abstract: PURPOSE:To obtain a low-noise oscillation output signal high in purity by combining an oscillation circuit using a crystal vibrator and a current mirror circuit which delivers plural signals. CONSTITUTION:A drive current ig for a crystal vibrator 20 is led to a current mirror circuit 30 and two currents (ID + ig) which are DC biased are extracted out of the circuit 30. A single current (ID + ig) is turned into a signal proportional to the amplitude of an AC component ig by a level control circuit 40. This signal controls the gains of a transistor Q5 of an oscillation circuit 10 to keep a constant amplitude of the current ig. While the other current (ID + ig) is turned into an oscillation output by an output buffer 50 after the AC component of said current is taken out. In such a way, a low-noise oscillation output signal high in purity is obtained.

Title: Logic circuit
Inventor: IKEDA KATSUJI
IPC: H03K19/0175
Filed: 1989-09-06
Abstract: PURPOSE:To increase number capable of mutual connection of output terminals when the drive capability of a three-state buffer is increased by providing n-set of common signal lines connecting relevant outputs of the three-state buffer in common and a means integrating the common signal lines. CONSTITUTION:Output terminals 20-22 corresponding to three output terminals of each three-state buffer are connected in common and they are integrated by a logic gate 4. Thus, since plural signal lines are used, the signal lines up to the three-state buffer in the high impedance state viewed as a load from the output terminal of the three-state buffer in the enable state are connected in parallel. Thus, the combined impedance of the signal lines is lower and the addition of three-state buffers is attained. When the drive capability of each three-state buffer is increased, number of output terminals to be connected together is increased.
