    Study Notes

    RAM Overview

    • Random Access Memory (RAM) is volatile storage media that requires power to retain its data.
    • Static RAM (SRAM) is faster than Dynamic RAM (DRAM) but also more expensive.
    • DRAM is commonly used as the primary storage in systems and is slower and less expensive than SRAM.

    Types of RAM

    • Synchronous Dynamic RAM (SDRAM) uses the system clock for coordinated functioning with other components.
    • Single Data Rate SDR SDRAM can read/write one word of data per clock cycle.
    • Double Data Rate SDRAM (DDR SDRAM) can read/write two words per clock cycle and features 184 contact pins.
    • DDR2 SDRAM has 240 contact pins and can read/write four words of data per clock cycle.
    • DDR3 SDRAM also features 240 contact pins and improves bandwidth and data transfer rates compared to DDR2.

    DDR Specifications

    • DDR-333 is known as PC-2700, while DDR-266 has a peak transfer rate of 2133 MB/s.
    • Maximum data transfer for DDR3-1600 is 12800 MB/s.
    • DDR2-1066 is referred to as PC2-8500, while total bandwidth of DDR2-533 is 4266 MB/s.

    Memory Module Types

    • Dual In-line Memory Modules (DIMMs) utilize a printed circuit board (PCB) with separate electrical contacts on each side.
    • Most common memory module form factor for laptops is SO-DIMM, while MicroDIMM is used in sub-notebook devices.

    ECC and Non-ECC RAM

    • Error-Correcting Code (ECC) RAM can detect and correct errors, enhancing system reliability.
    • ECC RAM is typically more expensive and does not always provide better speed than non-ECC memory.

    Multi-Channel Memory Architecture

    • Color-coded memory slots indicate compatibility with multi-channel architectures which improve data bandwidth and performance.
    • To benefit from multi-channel architecture, matching types, speeds, and capacities of memory modules are required.

    Other RAM Types

    • Buffered memory (RDIMM) provides stability in memory-intensive environments and is typically used in high-end servers.
    • Single-sided memory modules may have chips on both sides, but generally consist of chips on one side only.

    Key Definitions

    • Parity bit: An extra bit used to check the integrity of data by counting how many bits are set to one.
    • Buffered memory enhances system stability and accuracy, making it preferable in critical server environments.
