Marilyn Jean Lang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System and method for accessing data between a host bus and a system memory bus where the system memory bus has a data path that is twice the width of the data path for the host bus
    Patent number: 6202120
    Abstract: A microcomputer system memory architecture and method allows the system memory to provide data access at high speeds in a burst mode. The architecture and method utilizes a system memory controller capable of performing the addressing of the system memory. The microprocessor and the system memory communicate via a high speed host bus. The system memory is comprised of multiple 64-bit system memory buses to permit high speed data transfer to the microprocessor in a burst mode without the need for an external cache.
    Type: Grant

  • Microprocessor burst mode with external system memory
    Patent number: 5732406
    Abstract: A microcomputer architecture and method allows for high processing speeds. A microprocessor constitutes the central processing unit. The microprocessor comprises an on-chip cache memory and is capable of reading data in a burst mode. The central processing unit and the system memory communicate by way of a high speed host bus. The system memory is comprised of multiple buses and is capable of delivering data to the microprocessor in a burst mode at high speeds. A memory controller addresses data locations within the system memory upon receipt of a first host address from the microprocessor. Accordingly, the microprocessor can access data in the system memory at an extremely fast rate when operating in a burst mode. High speed processing is accomplished without the need for an external cache.
