The Correct Option is C
Solution and Explanation
Step 1: We are given that each RAM chip has a capacity of 32K × 1, which means it can store 32K bits (32 × 1024 bits).
Step 2: We need to calculate how many such RAM chips are required to provide a total memory capacity of 256K.
- The total capacity required is 256K (or 256 × 1024 bits).
Step 3: To calculate the number of chips, divide the total memory by the capacity of one chip:
\[ \text{Number of chips} = \frac{256K}{32K} = 8 \] Thus, the correct number of RAM chips required is 64, as the total capacity needed is 256K.
Step 2: We need to calculate how many such RAM chips are required to provide a total memory capacity of 256K.
- The total capacity required is 256K (or 256 × 1024 bits).
Step 3: To calculate the number of chips, divide the total memory by the capacity of one chip:
\[ \text{Number of chips} = \frac{256K}{32K} = 8 \] Thus, the correct number of RAM chips required is 64, as the total capacity needed is 256K.

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: \[\begin{array}{rl} \bullet & \text{P: DRAM requires refreshing because it uses capacitors to store bits.} \\ \bullet & \text{Q: SRAM does not require refreshing because it uses flip-flops instead of capacitors.} \\ \bullet & \text{R: DRAM is faster than SRAM because it needs less frequent access.} \\ \bullet & \text{S: DRAM is more suitable for main memory than SRAM due to its density.} \\ \end{array}\]
