Identifying Memory Module


Memory Module - A device that are used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer.

  • Volatile memory is computer memory that requires power to maintain the stored information.
  • Non-volatile memory is computer memory that can retain the stored information even when not powered.

Types of Memory Module

Single inline memory module
30 Pin and 72 Pin SIMM Module



Dual inline memory module
DIMM - SDRAM Single Data Rate

Double data rate
DDR - Double Data Rate
Double data rate
DDR2 and DDR3

SO-DIMM  (Small outline dual in-line memory module)SO-DIMMs are a smaller alternative to a DIMM, being roughly half the size of regular DIMMs. used in systems which have space restrictions such as notebooks. 

  • 72 Pin SODIMM
  • 100 Pin Firmware SODIMM  (32 bit data transfer rate)
  • 144 Pin EDO SODIMM (64 bit data transfer rate)
  • DDR333 200-Pin SODIMM Memory (64 bit data transfer rate)
  • PC3200 DDR400 200-pin SODIMM (64 bit data transfer rate)
