DRAM

Definition(s)

Dynamic Random Access Memory

  • A memory technology which is periodically “refreshed” or updated – as opposed to “static” RAM chips which do not require refreshing. The term is often used to refer to the memory chips themselves. Varieties are:
    • CDRAM: Cache DRAM (contains static cache)
    • EDODRAM: Extended data out DRAM
    • EDRAM: Enhanced DRAM (contains a static memory buffer and cache controller)
    • SDRAM: Synchronous DRAM (added clock and burst addressing capability)
    • SGRAM: Synchronous Graphics RAM (a single port SDRAM)
    • WRAM: Window RAM (dual port video RAM)
    • VRAM: Video RAM (a dual ported DRAM, good for graphics)
