THREE-DIMENSIONAL STORAGE DEVICE USING WAFER-TO-WAFER BONDING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17848844 titled 'THREE-DIMENSIONAL STORAGE DEVICE USING WAFER-TO-WAFER BONDING
Simplified Explanation
The abstract describes a three-dimensional storage device that uses wafer-to-wafer bonding. It consists of two chips: the first chip has a substrate and a peripheral circuit region with control logic, while the second chip has a substrate and three-dimensional arrays of non-volatile memory cells. The second chip is stacked on top of the first chip, with the control logic circuit on the opposite surface of the second substrate.
- The storage device uses wafer-to-wafer bonding to stack two chips together.
- The first chip contains a control logic circuit to control the operation modes of the non-volatile memory device.
- The second chip contains three-dimensional arrays of non-volatile memory cells.
- The second chip is stacked on top of the first chip, with the control logic circuit on the opposite surface of the second substrate.
Potential Applications
- This technology can be used in various electronic devices that require high-density storage, such as smartphones, tablets, and laptops.
- It can also be applied in data centers and servers to increase storage capacity and improve performance.
Problems Solved
- The three-dimensional storage device solves the problem of limited storage capacity in electronic devices by stacking multiple memory chips together.
- It also addresses the need for faster and more efficient storage solutions by integrating control logic circuits within the stacked chips.
Benefits
- The wafer-to-wafer bonding technique allows for compact and efficient stacking of chips, enabling higher storage density.
- The integration of control logic circuits within the stacked chips reduces the need for external control circuits, saving space and improving overall performance.
- The three-dimensional storage device offers increased storage capacity and improved data access speeds, enhancing the user experience.
Original Abstract Submitted
Provided is a three-dimensional storage device using wafer-to-wafer bonding. A storage device includes a first chip including a first substrate and a peripheral circuit region including a first control logic circuit configured to control operation modes of the non-volatile memory device and a second chip including a second substrate and three-dimensional arrays of non-volatile memory cells. The second chip may be vertically stacked on the first chip so that a first surface of the first substrate faces a first surface of the second substrate, and a second control logic circuit is configured to control operation conditions of the non-volatile memory device and is arranged on a second surface of the second substrate, the second surface of the second substrate being opposite to the first surface of the second substrate of the second chip.
