Show answer & explanation
Correct answer: C
First, convert the target memory size to bits: 2 Mbytes equals 16 Megabits (since 2 * 8 = 16).
Next, determine the capacity of a single chip: 256k × 1 equals 256 Kilobits.
Divide the total required bits by the chip capacity: 16 Mbits / 256 Kbits = 16384 / 256 = 64 chips.
