# Industrial Specification: Memory Module (RAM/ROM)

## 1. Technical Definition
A hardware component that provides temporary (RAM) or permanent (ROM) data storage for processing units.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **1.2-1.35 V (DDR4), 1.1-1.25 V (DDR5), 0-85°C ambient temperature**. Failure boundary: **Voltage exceeding 1.5 V (DDR4) or 1.4 V (DDR5) for &gt;10 ms, temperature &gt;95°C junction, current density &gt;1×10⁶ A/cm²**, Mechanism: **Electromigration at current densities exceeding Black's equation threshold (J &gt; 1×10⁶ A/cm²), dielectric breakdown at electric fields &gt;10 MV/cm, thermal runaway above 95°C junction temperature**.

### 2.2 FMEA (Failure Mode & Effects Analysis)

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the difference between RAM and ROM modules in your product line?
**A**: RAM (Random Access Memory) modules provide temporary, high-speed data storage that clears when power is off, ideal for active processing. ROM (Read-Only Memory) modules offer permanent, non-volatile storage for firmware and essential system data that persists without power.

### Q: What materials ensure the durability of your memory modules?
**A**: Our modules use silicon wafers for memory chips, copper traces for conductivity, plastic substrates for structural integrity, and gold or high-quality solder contacts for reliable connections and corrosion resistance in demanding environments.

### Q: Can you customize memory modules for specific industrial applications?
**A**: Yes, we offer customization including specific memory chip configurations, PCB substrate designs, and contact pin layouts to meet exact specifications for computer, electronic, and optical manufacturing applications.
