1.2 Understanding RAM: Types, Configurations, and Applications Flashcards
What is RAM?
RAM (Random Access Memory) is volatile memory that temporarily stores data for running programs and processes.
What is DRAM?
Dynamic RAM - Stores data dynamically and must be constantly refreshed to retain it.
What is SRAM?
Static RAM - Faster than DRAM because it doesn’t require constant refreshing.
What is SDRAM?
Synchronous DRAM - Operates in sync with the system clock, improving the efficiency of data handling.
What is DDR RAM?
Double Data Rate - Transfers data on both the rising and falling edges of the clock cycle, doubling the transfer rate compared to single data rate memory.
What is DDR1?
First generation of DDR, largely obsolete today.
What is DDR2?
Improved speed and power efficiency over DDR1.
What is DDR3?
Supports up to 16 GB per module and offers better performance than DDR2.
What is DDR4?
Current standard, supporting up to 64 GB per module with higher speeds and lower power consumption.
What is DDR5?
Latest version, with improved speed and power efficiency for modern workloads, often used in gaming and high-performance systems.
What is DIMM?
Dual In-line Memory Module - Used in desktops and servers, offering higher capacity.
What is SO-DIMM?
Small Outline DIMM - Used in laptops and small-form-factor PCs. Smaller form factor.
What is MicroDIMM?
Even smaller, used in ultra-portable devices.
What is Multi-Channel Memory?
Allow simultaneous data access across multiple modules, increasing bandwidth and performance.
What is Non-ECC RAM?
Common in consumer systems (desktops and laptops) and faster but lacks error correction.
