Latest Patents

Omori holds a patent for a multi-port cache memory. The conventional multi-port cache memory, which is formed by using multi-port cells, is excellent in its operating speed. However, the integration area of the constituent multi-port cells increases in proportion to the square of the number of ports. Thus, if it is intended to decrease the cache miss probability by increasing the storage capacity, the chip size increases correspondingly, which raises the manufacturing cost. On the other hand, the multi-port cache memory of the present invention is formed by using one-port cell blocks adapted for a large storage capacity. This design allows for the provision of a multi-port cache memory with a large storage capacity and reduced integration area, which has a large random access bandwidth and is capable of parallel access from multiple ports. This innovation is particularly suited for advanced microprocessors that require a small cache miss probability.
