Abstract
A network interface device includes a random access memory used as a transmit and receive buffer for transmission and reception of data between a host computer bus and a packet switched network. The network interface device includes a memory controller that determines whether a complete frame is stored in the random access memory and also determines an amount of data available to be read from the oldest received frame. A host CPU is able to access this information and determine whether to read the data or read the data at a later time.
