Assume that the largest decoder that can be used in an m x1RAM chip has 14 address inputs and that coincident decoding isemployed. In order to construct RAM chips that contain more one-bitwords than m, multiple RAM cell arrays, each with decodersand read/write circuits, are included in the chip.
a) With the decoder restrictions given, how many RAM cell arrays are required to construct a 2G x 1 RAM chip?
b) Show the decoder required to select fromamong the different RAM arrays in the chip andits connections to address bits andcell arrays select (CS) bits.
