Title: Semiconductor memory device
Inventor: MAKINO HIROYUKI
IPC: G11C11/41
Filed: 1987-05-19
Abstract: PURPOSE:To suppress fluctuation of access time, by providing bit-line clamping circuits which fix the readout low levels of bit lines at fixed values by using the Schottky barrier heights of Schottky diodes. CONSTITUTION:First and 2nd bit-line clamping circuits 20 and 30 are provided and the readout low levels of bit lines N5 and N6 are fixed to 0.3V by using the Schottky barrier heights 0.3V of Schottky diodes 14 and 17. At the time of readout, both of a word line N4 and bit-line selecting signal line N10 are set to high levels and a memory cell 1 is selected. Then data of a high level 0.7V and low level 0.3V are read out to the bit lines N5 and N6 and, furthermore, data of a high level 0.5V and low level 0.3V are read out to I/O lines N8 and N9. Thus the 0.3V of the low level is fixed regardless of the fluctuation of access time by the memory cell 1.

Title: Logic circuit device
Inventor: SUYAMA KATSUHIKO
IPC: H03K19/0944
Filed: 1987-05-19
Abstract: PURPOSE:To stabilize a circuit operation by maintaining an impedance ratio constant even when it is composed of any of a NOR gate and a NAND gate, and maintaining a logic threshold voltage invariable at each gate. CONSTITUTION:An input signal is applied by a NOR gate to the gate electrodes A, B of driving FETs 11D, 12D to obtain an inverted logic signal from an output terminal X, this signal is level-shifted by a source follower, and output from a terminal X'. The two FETs 11D, 12D are connected in parallel, and since either one FET is cut OFF in operation, the W/L at the driving FET side is the same as that of one driving FET, and the value becomes 10. Since the gate electrode of the load FET 12L is connected to a power line VDD at the load FET side, an element for affecting the influence to current/voltage characteristic becomes only the FET 11L. Accordingly, the W/L ratio at the load FET side becomes 6, and the impedance ratio becomes 0.6. Thus, the logic function per gate is strengthened, and the performance in the circuit operation can be enhanced.
