- **Caution**: 

### Q: What is the primary function of a sense amplifier in memory systems?
**A**: A sense amplifier detects and amplifies minute voltage differences from memory cells (typically in the millivolt range) to reliably determine whether a stored bit represents a 0 or 1, enabling accurate data retrieval in memory devices like DRAM and SRAM.

### Q: What materials are commonly used in sense amplifier manufacturing?
**A**: Sense amplifiers are primarily fabricated using semiconductor silicon substrates, with copper or aluminum metal interconnects for wiring, and dielectric materials for insulation between conductive layers in integrated circuit manufacturing processes.

### Q: How does the differential pair design improve sense amplifier performance?
**A**: The differential pair configuration compares voltage signals from complementary bit lines, providing common-mode noise rejection, increased sensitivity to small voltage differences, and faster response times for reliable data detection in high-speed memory applications.
