Build a 4K*12-bit RAM using: 2K*8-bit and 2K*4-bit RAMs Decoders Multiplexers Each RAM has the following input/outputs: Inputs I_m-1 .. l_0: Data input (Used during writes operations) A_n-1 .. A_0: Address input (Used during read and writes operations) CS: Chip Select: Used to enable a chip to perform the requested operation as indicated on the control inputs. R/!W: Read/!Write: performs a read when the input value is 1, and performs a write when the value is 0. Outputs O_m-1 .. O_0: Data output (Used during read operations)
