Different types of memory

The memory types are:

SIMM - Single-Line Memory Modules: Used to store single row of chips which are soldered onto Printed Circuit Board.

DIMM – Dual-Line Memory Modules: Used to store two rows of chips which are soldered onto printed circuit board and enables to contain two times memory than SIMM

DRAM – Dynamic Random Access Memory: It holds data for short time period and will be refreshed periodically.

SDRAM - Static RAM – Holds data and refreshing does not required. It is faster than DRAM.

Flash Memory: A non volatile, rewritable and solid state memory which performs the functions of both RAM and hard disk combined. Data is retained in the memory, in case of power loss. It is ideal for printers, cellular phones, digital cameras, pagers.

Shadow RAM: Allows the moving of selected parts of BIOS code that is available in ROM to the faster RAM.
