A 3D IC structure includes multiple die layers, such as a top die layer and a bottom die layer. The top die layer and/or the bottom die layer each includes devices such as computing units, Analog-to-Digital converters, analog circuits, RF circuits, logic circuits, sensors, Input/Output devices, and/or memory devices. The devices on the first and the second die layers are laterally surrounded by, or adjacent, vertical interconnect structures (VIS).

A memory device is provided. A first sub-block of the memory device includes first memory cells arranged in a first row and connected to a first bit line and second of memory cells arranged in a second row and connected to a first complementary bit line. The first memory cells and the second memory cells are connected to word lines in a first connection pattern. A second sub-block of the memory device includes third memory cells arranged in a third row and connected to a second bit line and fourth memory cells arranged in a fourth row and connected to a complementary second bit line. The third memory cells and the fourth memory cells are connected to the word lines in a second connection pattern that is different from the first connection pattern.

Memory device

A 3D IC structure includes multiple dies, such as a top die and a bottom die. The top die and/or the bottom die can each include devices such as computing units, Analog-to-Digital converters, analog circuits, RF circuits, logic circuits, sensors, Input/Output devices, and/or memory devices. One or more vertical interconnect structure (VIS) cells are formed adjacent one or more sides of the device. A VIS is formed in some or all of the VIS cells. One or more non-sensitive circuits, such as repeaters, diodes, and/or passive circuits (e.g., resistors, inductors, capacitors, transformers), are disposed in at least one VIS cell.

Vertical interconnect structures with integrated circuits

The invention uses the control circuit formed on the silicon wafer to detect the leakage current of transistor formed on the depletion mode GaN wafer and then adjust the gate voltage of the depletion mode GaN transistor according to the detected leakage current. Essentially, the gate voltage is reduced or viewed as made more negative when the detected leakage current is larger a specific value. Thus, the gate voltage can be gradually adjusted to approach a specific threshold voltage that right block the leakage current. In other words, by making the gate voltage more negative when non-zero leakage current is detected and even by making the gate voltage more positive when zero leakage current is detected, the depletion mode GaN transistor can be adjusted to have an acceptable or even zero leakage current, a high reaction rate and an optimized efficiency.
