Data buffer memory of the first-in, first-out type comprising a fixed input and a variable output

摘要

A data buffer memory of the "first-in, first-out" type, having a fixed input by which data are applied to the buffer, and an output bus by which data are extracted from the buffer. The buffer includes logic means whereby a variable output location can be selected. The logic means determines by means of status signals in cooperation with signals applied from outside the buffer, where data are read from the buffer and, if necessary, when data in the buffer are to be shifted further from the input location.
