| Term | Definition |
|---|---|
| SO-DIMM (small outline DIMM) | a smaller version version of DIMM for laptops |
| RIMM | an older version of DIMM |
| SIMM (sinlge inline memory module) | has a different width of the data path that each type of module accommodates and the way the data moves from the system bus to the module |
| synchronous DRAM (SDRAM) | the first DIMM to run synchronized with the system clock |
| Double Data Rate SDRAM (DDR SDRA< or SDRAM II or DDR) | an improved version of SDRAM, it runs twice as fast as regular SDRAM |
| single-sided | memory chips installed on one side of a module |
| double-sided | memory chips installed on both sides of the module |
| memory bank | the memory a processor addressees at one time and is 64 bits wide |
| dual ranked | double sided DIMMs that provide two 64 bit memory banks |
| single ranked | DIMMs that provide one 64 bit memory bank |
| single channel | the memory controller can access one DIMM at a time |
| dual channel | the memory controller can access two DIMM at a time |
| triple channels | the memory controller can access three DIMM at a time |
| ECC (error correcting code) | ECC can detect an error but not prevent it |
| parity | older SIMMs used parity as their error checking system |
