Latest Patents

Yamamoto holds a patent for an "Apparatus and method for reading, writing, and refreshing memory." This invention provides a computer memory system that can handle memory requests for both virtual and physical addresses. The system determines the type of address and sets a virtual/physical bit accordingly. It compares row address bits to registers containing either virtual or physical row addresses. When a match occurs, column address bits select the requested memory element without needing a virtual-to-physical translation. If there is no match, a physical address is obtained, which is then used to load a new row address into a latch. The patent also describes a refresh cycle that preserves locality information.
