Problem: What are common RAM Terms?



Memory Terms
Cache memory Very fast temporary memory located between the processor and the main memory. This memory holds previously accessed data for faster subsequent access.
Dual-ported RAM A type of RAM that allows two memory addresses to be read at once. The most popular type of dual-ported RAM is VRAM, which is used mostly for video memory.
ECC RAM (error checking and correcting random-access memory) A type of memory that actually corrects errors rather than simply detecting them, as its predecessor, parity RAM, does. ECC RAM is both cheaper and more advanced than parity RAM and is therefore common on workstations.
EDO RAM (extended data out RAM) Memory that allows the processor to start accessing another memory location while still receiving data from the previous access. No longer the best choice for desktops, this type is predominant in large servers.
RAM (random-access memory) The type of memory in which a PC stores data temporarily while it’s working with that data. Most of the other entries here are different flavors of RAM.
RAMbus or RDAM (Rambus DRAM) A faster, currently more expensive way of using RAM that can perform more than one operation per clock tick, yielding speeds of up to 800 MHz. Currently, this type is only found on high-end systems.
SRAM (static RAM) A very fast type of memory, usually used only for a cache.
SyncDRAM or Synchronous DRAM or DRAM (Synchronous Dynamic RAM) The most popular flavor of RAM used on desktops today. Its accesses are synchronized with the memory bus clock, so it can perform a memory access with each clock tick. The clock speeds range from 66 MHz to 133 MHz. Currently, 100 MHz (often referred to as PC-100) is the most common.
VRAM (Video RAM) A type of dual-ported RAM tailored for use with video adapters.
Windows RAM A special version of dual-ported RAM optimized for use on graphical-interface systems such as Windows.
