Filed: 1991-10-21
Abstract: PURPOSE: To prevent malfunction due to high-frequency address transition. CONSTITUTION: The input stage 10 of an input buffer circuit is connected with a delaying stage 16 and with a transition detecting circuit 20. The output terminal of the delaying stage 16 is connected with a path gate 18, which is controlled by the output of the detection circuit 20 and a latch 30 is connected to a side opposite to the gate 18. The detection circuit 20 generates a pulse in response to transition and the gate 18 is turned off for the period of the length of the pulse and the latch 30 supplies while maintaining the state of inputting before transition. After completing the pulse, the new value of an input signal is latched and supplied to a circuit.  As the path gate 18 is turned off for the period of a transition detecting pulse, short and accidental transition at an input terminal is separated from the latch 30 by the gate 18 and does not appear at the output terminal of the input buffer terminal.

Filed: 1984-12-24
Abstract: PURPOSE:To prevent bonding wires from being cut, by sealing the periphery of a semiconductor pellet with melted resin which is flowed therein in the direction of the major axes of the flatted bonding wires. CONSTITUTION:After a semiconductor pellet 11 is bonded onto a pellet bed 12, the pad sections and internal leads 13a, 13b of a lead frame are bonded by flatted bonding wires 21 each having a cross sectional ellipse shape. The peripheral space surrounding the semiconductor pellet 11 including the internal leads 13a, 13b and bonding wires 21 is enclosed by a mold, and epoxy-based melted resin 15 is filled into the mold to seal the semiconductor pellet 11 with the resin.
