Latest Patents
Monma's latest patents include a semiconductor device featuring a test circuit. This innovative device comprises a test signal generating circuit that produces a test signal with an arbitrary frequency. It also includes a first buffer that selectively outputs either the test signal or an external input signal. The design incorporates at least one test circuit that receives the output signal from the first buffer, along with an external output terminal and a logic circuit. A second buffer is utilized to supply either the test signal from the test circuit or the output signal of the logic circuit to the external terminal. Additionally, a switching signal generating circuit is responsible for generating switching signals for both buffers. This configuration allows for the state of the test circuit to be checked using the test signal, indirectly determining the state of the logic circuit.
Another notable patent is for a chip-on-chip type integrated circuit device. This invention includes a circuit designed to check the integrity of interconnections between chips in a chip-on-chip IC device. The circuit is fabricated in specific portions on both the lower and upper chips, located in peripheral areas between the inner logic circuit of each chip and the corresponding bonding pads. Selection circuits connect the inner logic circuit signal terminals to the bonding pads and can be switched by control signals to either isolate the inner logic circuit or allow normal operation. This innovative method enables the testing of the integrity of interconnections, ensuring reliable performance.
