Work Step by Step
Using a large memory cell gives us the advantages:
- Higher precision and range: Larger cells can store much bigger integers or more precise floating-point values.
- Fewer memory accesses: Fewer cells are needed to store large data values, improving access speed for big data types.
- Better performance for large numbers: Arithmetic operations on 64-bit numbers are faster than combining multiple 8-bit values.
The disadvantages would be:
- Memory inefficiency: Small data values (like characters) waste space when stored in large 64-bit cells.
- Higher power consumption and cost: Larger cells mean more transistors per cell and more complex circuitry.
- Slower for small operations: Handling unnecessarily large word sizes can slow down small data processing tasks.
For a 64 bit memory cell the largest positive and negative values will be $2^{63}-1$ and $-(2^{63}-1)$.
If two cell are used then the largest positive and negative values will be $2^{127}-1$ and $-(2^{127}-1)$.
