A 32 kB RAM is formed by 16 numbers of a particular type of SRAM IC. If each IC needs 14 address bits, what is the IC capacity?
1. 32 kbits
2. 16 kbits
3. 8 kbits
4. 4 kbits

Correct Answer - Option 2 : 16 kbits

The total capacity is given a 32 kB. This can be written as:

32k × 8 bits = 256k bits

Since 16 IC's are used, each IC will provide:

$\frac{256}{16}=16~kbits$

∴ 14-bit address will give 16k memory locations, i.e. each chip can address 16k memory locations.

So, the capacity of each IC = 16k bits.
