# DRAM Simulation Project

This project provides a comprehensive simulation framework for analyzing DRAM memory systems using DRAMsim3. The focus is on evaluating performance characteristics of different memory architectures, particularly HBM (High Bandwidth Memory), DDR3, and DDR4.

Key features include:
- Detailed simulation of memory timing, power consumption, and thermal behavior
- Support for various DRAM standards (DDR3, DDR4, HBM, HMC, GDDR)
- Performance comparison across different workloads (random, stream, matrix operations, etc.)
- Automated benchmark generation and visualization tools
- Thermal modeling capabilities for analyzing heat distribution

The project includes pre-configured memory controller settings and provides tools for generating custom memory access patterns. It's particularly useful for:
- Computer architecture research
- Memory system design optimization
- Performance prediction of real-world applications
- Educational purposes in computer engineering

## Project Structure

- `DRAMsim3-1.0.0/`: The main DRAMsim3 simulator source code
  - `configs/`: Configuration files for various DRAM types (DDR3, DDR4, HBM, etc.)
  - `src/`: Source code of the simulator
  - `scripts/`: Python scripts for analysis and visualization
- `build/`: Build directory for compiled binaries
- `*.png`: Performance comparison charts
- `*.csv`: Benchmark results

## Getting Started

1. Clone this repository
2. Build DRAMsim3:
   ```bash
   cd DRAMsim3-1.0.0
   make
   ```
3. Run simulations:
   ```bash
   ./dramsim3main configs/HBM_4Gb_x128.ini
   ```

## Features

- Supports various DRAM standards: DDR3, DDR4, HBM, HMC, GDDR
