Title: Semiconductor memory and logic circuit
Inventor: ARAKAWA FUMIHIKO
IPC: G11C11/414
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To realize stable operation, speedup and high integration even in a MOS transistor having progressed fineness and a low threshold value by putting a bit line in high electric potential without largely increasing the number of transistor elements and a working current. SOLUTION: When the bit line BL1 is higher than the bit line BR1 in electric potential at the time of reading information of a memory cell CM1, since a large current IRL is made to flow to a common data line CDL more than to the common data line CDR through a sense circuit resistance RFL by differential amplifying operation, collector potential of the transistor QEL becomes higher than by IRL×RFL that of the common data line CDL, and a sense circuit output SGOL becomes high. When an input impedance is low and currents IRL, IRR are varied in a parallel-parallel type negative feedback amplifier circuit, common data lines CDL, CDR are operated at a high speed because of small voltage amplitude.  Also, direct feedback is executed from a collector of transistors QEL, QER to common data lines CDL, CDR, whereby a SRAM having a high speed and high integration which corresponds to the MOS transistor having the low threshold value is allowed.

Title: Output protection circuit
Inventor: YAMANAKA TAKASHI
IPC: H03K19/0175
Filed: 1986-10-22
Abstract: PURPOSE:To prevent the deterioration in the characteristic of a transistor (TR) by connecting a source of the 3rd TR to a common source/drain of two output TRs, connecting the drain to the gate of the output TR of the power supply side and connecting the gate to an output signal of a control circuit so as to suppress the increase in a base current. CONSTITUTION:Since a gate of a TR 2 is 0V when the level of an output terminal Dout drops to 0V or below, when the level is lower than the threshold voltage of the TR, the TR approaches the on-state. Then the gate of the output protection TR is lower slightly than the threshold voltage and higher than 0V, then the TR 3 is turned on earlier than the TR 2 to decrease the potential of a connecting point A connecting to the gate of the TR 2. Even if the level of the terminal Dout is lowered to the potential below 0V and over the threshold value, the TR 2 receiving a high voltage to its drain is not turned on and no current flows. Although the TRs 1, 3 are turned on, since the level of the drain is 0V respectively, the increase in the base current is suppressed lower.

A semiconductor element 10 is enclosed in an LSI case 7 while the heat conductive plate 6 of the LSI case 7 is installed on the heat conductive side of the semiconductor element 10. Since the female screw 11 wherethrough the male screw 4 for installing the fins 5 for stacking is threaded is threaded in the central part of the heat conductive plate 6, the lowermost fin 5 for stacking can freely be attached to and detached from the heat conductive plate 6. Accordingly, specific number of the fins 5 for stacking can be installed on the heat conductive plate 6 thereby enabling the heat generated by the semiconductor element 10 to be radiated through the heat conductive plate 6.
