    • A complementary bipolar transistor circuit characterized by the same output impedance for positive and negative input voltage transitions, only a single collector path delay between input and output for both senses of input voltage transitions and very low standby power consumption. Provision is made for simultaneously actuating an emitter follower series-connected first pair of complementary transistors with signals having voltage swings which are only a fraction of the V.sub.be necessary to forward bias each base-emitter diode of the first pair of transistors. The actuation is accomplished using a second pair of complementary transistors having collector electrodes connected to respective bases of the first pair of transistors of similar kind. One of the remaining electrodes of each of the second pair of transistors are connected to each other.In a driver circuit species of the invention, the bases of the second pair of transistors are connected to each other and receive the input signal. In a logic circuit species of the invention, the emitter of one of the second pair of transistors is connected to the base of the other of the second pair of transistors. NOR logic is performed by connecting additional transistors in parallel with said one of the second pair of transistors, the bases of the additional transistors receiving respective logic input signals. The output from the driver circuit as well as from the logic circuit is derived from the commonly connected emitters of the first pair of transistors. The first pair of transistors conduct only during the transitions of the input signals.

    • Low voltage, low power transistor driver/receiver and logic circuits are disclosed comprising a pair of NPN transistors, the base of the first transistor being directly connected to an input terminal and, via a resistor, to the base of the second transistor. A third NPN transistor is connected with the second transistor in series circuit across a low voltage power supply. The junction between the series-connected transistors is coupled to an output terminal. A diode is connected between a point on the resistor and the collector of the second transistor to prevent saturation. The emitter of the second transistor is connected through a small or zero resistance to one terminal of the power supply. The down level at the output terminal is held by a transistor or diode clamp connected between the base of the third transistor and the other terminal of the power supply.Various embodiments of the circuits are disclosed to provide driver and logic functions and to permit tailoring of the circuits to various load conditions requiring different output signal swing amplitudes and different response times.

    • A packaging substrate (10) is populated with memory chip cube(s) (40) and horizontally mounted interconnect chip(s) (19) mounted on the substrate which are joined during assembly using two kinds of lead tin solder alloys to form memory chip cube. One is a high melting point lead tin alloy (HMA), the other is a lower melting point lead tin alloy (LMA). The memory chip pairs (11) of the memory cube are formed by placing functional memory chips over another functional memory chips before they were diced. The chip pads of the individual memory chips and the lead tin pads of the memory chips within the wafer are aligned and the high melting point lead tin solder is reflowed, forming memory chip pairs. The memory cube (42) is formed by joining the memory chip pairs together in a boat (30) with a silicon bar (41) maintaining spacing during manufacture. The memory chip cube (42) as well as the supporting chips are then placed and joined to the packaging substrate. The supporting silicon bar is removed from the memory chip cube (42) by re-heating the cube after it is joined to the packaging substrate. The package is completed by following with capping of the chip package of the paired memory chip cube with its attached packaging substrate by attaching to the base member substrate an appropriate heat sink after appropriate I/O flex lines are in place.
