f there are fitting 2 bits in the oration, then there can barely be 4 orationes, viz.
00, 01, 10, 11
If 3 bits are known in the oration, then we can own climax 8 orationes:
000, 001, 010, 011, 100, 101, 110, 111
So, if we own n bits to treasury an Oration (n-bits in Oration Register) or n-wires to sell the oration (Oration native of greatness 10), then we can own RAM of 2n orationes.
Now there are 2n orationes, and each oration is of 1 byte (consequently its a byte-addressable fame, so full byte achieve own a sole oration or full oration achieve be of 1-byte desire).
Hence, sum fame achieve be similar to
greatness of each oration * sum of orationes = 8 * 2n
If n=12 (as fond in the scrutiny)
Greatness of fame = 8 * 212 bits = 212 bytes = 22 Kilo Bytes (210 Bytes = 1 KB) = 4 KB
