Latest Patents

One of Ogura's latest patents is titled "Apparatus and method for masking input of invalid data strobe signal." This invention aims to provide a data fetch circuit that reliably cuts off the transmission of a high impedance state of a data strobe signal, even when manufacturing or operational conditions change. The circuit includes an RL measuring part that measures a latency measurement value from the input of a read instruction signal to the valid edge of a data strobe signal. Additionally, it features an RL count comparing part that outputs a signal to cancel the cut-off of the data strobe signal after a specified wait time.

Another notable patent is the "Memory circuit testing system, semiconductor device, and memory testing method." This invention allows a semiconductor device to perform refresh tests on multiple individual memories within the same chip while preventing excessive testing during the refresh process. The first testing circuit issues a refresh command to a memory circuit, which refreshes its memory cells until the second testing circuit completes its writing process, ensuring synchronized refresh test times.
