Memory

How do we get larger amounts of memory?

Think of memory as abstraction

4K memory: like byte array M[4095]

Give memory index of byte, get data value back

Use 4 1K chips

Each chip has elements C[0] up to C[1023]

Chips are numbered 00, 01, 10, 11

Each chip contains 1024 of the elements (0 to 1023, 1024 to 2047, etc.)

Where is element M[1025]?

Chip 01 at index 1

Where is element M[3071]?

Chip 10 at index 1023
