Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFTo increase the word size (i.e., the number of bits in each word that the CPU can read or write in one operation), the system typically uses parallel memory modules.
🧠 How it works:
-
If each memory chip/module is, for example, 8 bits wide, and you need a 32-bit word, then you can connect 4 such modules in parallel.
-
Each module contributes a portion (like 8 bits) of the full word.
-
All modules are accessed simultaneously, giving you a wider word size.
Additional Information
| Option | Why Incorrect |
|---|---|
| 1) Memory interleaving | Increases speed, not word size; spreads addresses across modules. |
| 2) Memory mapping | Maps memory addresses to devices; relates to address allocation, not word width. |
| 3) Address decoding | Used to select memory locations; controls which module responds, not how wide the data is. |
