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 are needed to provide a memory capacity
of 64 Kbytes memory is
Qn #413
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:
P: DRAM requires refreshing because it uses capacitors to store bits.
P: DRAM requires refreshing because it uses capacitors to store bits.
Q: SRAM does not require refreshing because it uses
flip-flops instead of
capacitors.
R: DRAM is faster than SRAM because it needs less frequent access.
S: DRAM is more suitable for main memory than SRAM due to its density.
R: DRAM is faster than SRAM because it needs less frequent access.
