A computer system has 16-bit wide address/data bus that uses RAM chips of \(4K \times 8\)-bit capacity. The number of RAM chips needed to provide a memory capacity of 64 Kbytes memory is
Show Hint
Convert KB to bytes and divide by chip capacity to find required number of chips.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Total memory required = 64 KB = 64 × 1024 = 65536 bytes
Step 2: Each RAM chip has capacity = \(4K = 4 \times 1024 = 4096\) bytes
Step 3: Number of chips required = \(65536 \div 4096 = 16\)
Step 2: Each RAM chip has capacity = \(4K = 4 \times 1024 = 4096\) bytes
Step 3: Number of chips required = \(65536 \div 4096 = 16\)

Top Questions on Computer Memory
- Dynamic RAM (DRAM) stores each bit of data in a separate capacitor. Due to leakage, the stored charge tends to dissipate over time and needs to be refreshed periodically. Consider the following statements: \[\begin{array}{rl} \bullet & \text{P: DRAM requires refreshing because it uses capacitors to store bits.} \\ \bullet & \text{Q: SRAM does not require refreshing because it uses flip-flops instead of capacitors.} \\ \bullet & \text{R: DRAM is faster than SRAM because it needs less frequent access.} \\ \bullet & \text{S: DRAM is more suitable for main memory than SRAM due to its density.} \\ \end{array}\]
