Latest Patents
One of Yamada's latest patents is a memory apparatus and method capable of setting the attribute of information. This innovative cache memory apparatus allocates memory regions based on information attributes, allowing for efficient access before caching is implemented. This design significantly reduces the need for duplication among different chips corresponding to various information attributes. In a multiple data processing environment, cache memory regions are allocated for each data processor, ensuring that the required memory regions are accessed according to the data processor's specifications. Additionally, to prevent data collisions during substantial rewrites of main memory data, Yamada's system stores data representing the type of access, nullifying all data signals stored in each way in response to access changes.
Another notable patent is a computer system with cache memory having an address mask register. This system features multiple cache memories that store data corresponding to parts of the main memory address space without overlapping. This design allows for easy capacity increases of the cache memory, utilizing an address mask register to allocate portions of the main memory address space stored in each cache.
