BUFFER MEMORY SYSTEM

A memory system having a memory for storing data messages from a digital computer and display means for reading data messages from the memory at a rate independent of writing data messages. A counter means counts the number of data messages written into the memory and the number of data messages read from the memory to determine the locations in the memory for writing and reading, respectively. A queue of data messages is stored in the memory whenever the writing rate exceeds the reading rate. Data messages in such a queue are read in the order written.
