“Each register in the memory has a different address—a pattern of bits by means of which you can access it—so registers are referred to as locations in memory. The memory contains Boolean logic blocks, which decode the address and select the location for reading or writing. If data are to be written at this memory location, these logic blocks store the new data into the addressed register. If the register is to be read, the logic blocks steer the data from the addressed register to the memory’s output, which is connected to the input of the finite-state machine.”
