Burst EDO | A refined version of EDO memory that significantly improved access time over EDO. |
CAS Latency | A method of measuring access timing to memory. |
C-RIMM | Placeholder for RIMM module that provides continuity so that every RIMM slot is filled. |
DDR2 | A version of SDRAM that that is faster than DDR and uses less power |
DDR3 | Version of SDRAM that is faster than DDR2 memory and that can use triple channels. |
Direct Rambus DRAM | Memory technology by Rambus and Intel that uses a narrow network-type system bus. |
Double Data Rate SDRAM | A type of memory technology used on DIMMs that runs at twice the speed of the system clock. |
DDR SDRAM | An abbreviation for Double Data Rate SDRAM. |
double-sided | A DIMM with memory chips installed on both sides of the module. |
dual channels | A motherboard feature that improves memory performance by providing two 64-bit channels between memory and the chipset. DDR and DDR2 memory can use dual channels. |
dual ranked | Double-sided DIMMs that provide two 64-bit banks. |
dynamic RAM (DRAM) | The most common type of system memory, it requires refreshing every few milliseconds. |
ECC (error-correcting code) | A chipset feature on a motherboard that checks the integrity of data stored on DIMMs or RIMMs and can correct single-bit errors in a byte. More advanced ECC schemas can detect, but not correct, double-bit errors in a byte. |
EDO (extended data out) | A type of outdated RAM that was faster than conventional RAM because it eliminated the delay before it issued the next memory address. |
