Title: Semiconductor storage device
Inventor: NAGAYAMA YASUHARU
IPC: H01L21/8242
Filed: 1987-06-10
Abstract: PURPOSE:To suppress noise due to capacitive coupling caused between bit lines by operating a sense amplifier amplifying a potential appearing on a bit line to a prescribed potential in two stages. CONSTITUTION:A generating circuit drive signal phi8 given to a sense amplifier drive signal generating circuit 1 descends from an H level to an L level, then a sense amplifier drive signal phi6 is restored to the L level from the H level, a transistor (Tr) Q18 is turned off to activate an N-channel sense amplifier SN. On the other hand, a sense drive signal phi7 rises from the L level to the H level to activate a P-channel sense amplifier SP through a TQ 15. Thus, bit line pairs BL, the inverse of BL are fixed to the intermediate potential between the H level and the L level. Then sense drive signals phi3, phi4 are changed respectively from the L to H level and from the H to the L level. Thus, the amplifiers SN, SP are activated and the lines BL, the inverse of BL of the intermediate potential are charged/discharged to the power potential Vcc and ground potential.

IPC: H04B10/572
Filed: 1981-09-16
Abstract: PURPOSE:To reduce the power consumption, by changing only the amplitude of a pulse signal with the DC bias current kept at a constant level and stabilizing an optical output. CONSTITUTION:A signal input is applied to a gate electrode 407 of the 2nd FET401 existing along with the 1st FET400.

Filed: 1983-08-10
Abstract: PURPOSE:To control two signals to a prescribed value with one pilot signal by controlling the signal which is attenuated in case of the pilot signal is transmitted through a coaxial cable, to a preliminarily expected value. CONSTITUTION:When the pilot signal attenuation in the 1st coaxial cable 10 is changed due to the temperature change or the like, an output level of the 1st amplifier section 16 and an attenuation control voltage are changed.

IPC: H04L1/00
Filed: 1993-05-26
Abstract: PURPOSE:To improve data transmission efficiency by calculating an error detection code, generating a frame pulse on which the error detection code is superimposed, and transmitting the frame pulse and data. CONSTITUTION:In a transmission device 100, a parity arithmetic circuit 3 calculates the parity of a specified arithmetic range of transmitted data. Then, a pulse width control circuit 4 generates the frame pulse having a pulse width corresponding to the value of the calculated parity. In a receiving device 200, a parity arithmetic circuit 8 calculates the parity of the data. On the other hand, a pulse width detecting circuit 5 extracts the parity based on the parity of the frame pulse, and a parity comparator circuit 6 compares the parity with the parity calculated by the circuit 8. When the compared result indicates coincidence, the data are judged to be normal, and when it indicates non-coincidence, the data are judged to be erroneous. Thus, the abnormality of a transmission line 7 or the like can be detected.
