Latest Patents

Among his latest innovations, Ishibashi has developed advanced content addressable memory (CAM) systems designed to reduce power consumption while increasing search operation speed. His patent details a mechanism where multiple bits of unit cells, each responsible for storing a data bit, are linked to a match line. This match line utilizes a charging current that is strategically restricted, allowing for improved operational efficiency. Specifically, it ensures that the charging current is smaller than that flowing during a one-bit miss state and larger when all bits in an entry match. Additionally, he has restricted the precharge voltage level of the match line to half or less of the power supply voltage. This inventive approach results in a significant reduction in power consumption during search cycles while simultaneously boosting the speed of search operations within content addressable memory systems.
