Latest Patents

Murase's latest patents include a memory circuit testing system and a semiconductor device that features a memory testing method. The semiconductor device is designed to perform refresh tests on multiple individual memories integrated into the same chip. This innovation prevents excessive testing during the refresh test process. When a first testing circuit enters a wait state, it issues a refresh command to a first memory circuit, which refreshes the memory cells until a second testing circuit also enters a wait state. This synchronization ensures that the refresh test time for both memory circuits is equal.

Another significant patent is a protection circuit aimed at safeguarding semiconductor devices from voltage fluctuations. This input protection circuit includes a conductor pattern that connects an input pad to an integrated circuit. It features mutually separated ground patterns on either side of the conductor pattern, along with gate patterns that form transistors extending continuously from one end of the conductor pattern to the other. This design enhances the protection of the semiconductor device against potential damage.
