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.

Data buffer memory of the first-in, first-out type comprising a fixed

A data buffer memory for the first-in, first-out type, having an input bus by which data are supplied to the buffer, and a fixed output from which data are transferred from the buffer. Each section of the buffer includes logic whereby a variable input location can be selected. Status signals are used to determine, in cooperation with signals supplied from outside the buffer, the location where data are to be written in the buffer and when these data in the buffer must be shifted to the output.

Data buffer memory of the first-in, first-out type, having a variable

A data buffer memory of the 'first-in, first-out' type, having an input bus by which data are applied to the buffer and an output bus by which data are taken up from the buffer. The buffer includes logic means whereby a variable input location and a variable output location can be selected. The logic means are provided for each section of the buffer and use status signals in co-operation with signals applied from outside the buffer, to determine where data are to be written in the buffer and where data are to be read from the buffer.
