  • Patent number: 6874064
    Abstract: A FIFO memory device includes a multi-port cache memory and an extended capacity memory (e.g., SRAM). The multi-port cache memory includes a data input port, a data output port, a first memory port that is configured to pass write data to the extended capacity memory during memory write operations and a second memory port that is configured to receive read data from the extended capacity memory during memory read operations. The multi-port cache memory includes at least a data input register and a multiplexer that is responsive to at least one path signal. The multiplexer is configured to enable a first memory path that routes first data from the second memory port to the data output port during first FIFO read operations that occur when the FIFO memory device is filled beyond a threshold level.
