For economy in electronic components and their interconnections a multiplex memory system for temporary storage of digital signals, especially digital video signals, is made up of memory units each of which stores the contents of the same bit place of different data words of the data arriving at the memory system. The corresponding bits of eight words are entered in parallel in each memory. The system can be configured with memory components presently available for any desired data word bit width without waste of storage capacity. For each multiplex memory plane constituted by the memory unit for a particular bit place, only two shift registers are needed for writing into and reading out of a RAM, provided that one of the two shift registers has a built-up in D register for parallel output, a feature that is commonly available commercially. This is much more convenient and economical than the requirement of three D registers per multiplex memory plane in a conventional multiplex memory.
