14. A 22-by-3 Bit Memory, Cont.


  • Decoder takes A[1:0] and asserts exactly one of its four outputs, pointing to a row of memory.

  • Each memory location yields a unique three-bit word.

  • Horizontal locations for data input and output are called word lines.

  • Entire circuit is a mux of output signals with built-in decoder for selection of data values.

     

  •   4-by-3 bit memory
