RAM Speed and Types

RAM Speed

• Measured in MHz (Megahertz) or GHz (Gigahertz)
• Refers to the rate at which the RAM can transfer data
• Faster RAM speed allows for:
  • Improved system performance
  • Increased bandwidth
  • Better multitasking capabilities

Types of RAM Speed:

• SDR (Single Data Rate) SDRAM: 66-133 MHz
• DDR (Double Data Rate) SDRAM: 100-400 MHz
• DDR2 SDRAM: 400-1066 MHz
• DDR3 SDRAM: 800-2133 MHz
• DDR4 SDRAM: 1200-3200 MHz
• DDR5 SDRAM: 3200-6400 MHz

Factors Affecting RAM Speed:

• Frequency: The rate at which the RAM can transfer data
• Latency: The time it takes for the RAM to respond to a request
• Timings: The delay between the RAM receiving a request and sending data
• Voltage: The power required to operate the RAM

Importance of RAM Speed:

• Faster RAM speed can improve overall system performance
• Essential for applications that require high bandwidth, such as:
  • Video editing
  • 3D modeling
  • Gaming

Computer Memory: RAM and ROM

ROM (Read-Only Memory)

• Permanently stores data that cannot be changed or written by a user
• Non-Volatile, meaning it retains its data even when the power is turned off
• Used for storing firmware, boot loaders, and other low-level system software
• Characterized by permanent storage, non-changeable data, and data retention when power is off

RAM (Random Access Memory)

• Temporarily stores data and applications while they are being used
• Volatile, meaning it loses its data when the power is turned off
• Used for running applications, storing data temporarily, and performing calculations
• Characterized by temporary storage, changeable data, loss of data when power is off, and faster access times compared to ROM
