Abstract
A network interface device having a random access memory for buffering data between a host bus interface and a media access controller includes a buffer controller configured for storing a data frame in combination with tracking and status information associated with the storage of the data frame. The memory controller is configured for writing receive frame data received from a media access controller into the random access memory. The tracking and status information is stored in memory locations contiguous with the data frame to enable a read controller operating in a separate clock domain to access the status information and the corresponding data frame as a single data unit. Moreover, the disclosed embodiment stores the status information at the beginning of the stored data unit, enabling a controller reading the buffer memory to immediately determine the status of the corresponding stored data frame.
