  • Methods and apparatus for high-speed mass storage access in a computer system
    Patent number: 5987627
    Abstract: An apparatus called a DataPort is disclosed for use in conjunction with a computer. The DataPort includes a private memory comprised of a high-speed, solid-state random access memory array. A public memory comprising a series of registers serves as an intermediary between the private memory array and a computer CPU local bus for memory access operations. The public memory includes staging registers which are used for conversion between the CPU local bus word size and the internal private memory word size as may be necessary, including pipelining as required. The DataPort also generates error correction codes (ECC) and stores the correction codes in the private memory, interleaved with data received from the CPU local bus, and checks the ECC codes to detect errors when data is read back out to the bus.

  • Linked file storage in a computer memory system
    Patent number: 5652865
    Abstract: A computer file system mechanism to use data port storage efficiently wherein lost or unused storage space is minimized and use of available storage maximized. The data port file system may be used as an augmentation of existing file system mechanisms or in complete replacement thereof. The data port file system may be implemented such that the information required to maintain the file system is always updated to the data port or such that the information required to maintain the file system is always located in system memory during computer operations. The data port file system may be implemented such that both methods are used.
