Burst EDO (BEDO) | a refined version of edo memory that significantly improved access time over ed. Bedo was not widley used because intel chose not to support it. |
CAS Latency (CL) | a method of measuring access timing to memory, which is the number of clock cycles required to write or read a column of data off a memory module. |
C-RIMM (Continuity RIMM) | A placeholder RIMM module that provides continuity so that every RIMM slot is filled. |
DDR2 | A version of SDRAM that is faster than DDR and uses less power .DDR2 |
DDR3 | An improvement over DDR and DDR2 that is faster and uses less power. DDR3 |
Direct Rambus DRAM | A memory technology by Rambus and Intel that uses a narrow network-type system bus. Memory is stored on a RIMM module. Also called RDRAM or Direct RDRAMDirect Rambus DRAM |
Double Data Rate SDRAM | A type of memory technology used on DIMMs that runs at twice the speed of the system clock.Double Data Rate SDRAM |
DDR SDRAM | An abbreviation for Double Data Rate SDRAM. DDR SDRAM |
double-sided | A DIMM with memory chips installed on both sides of the module.double-sided |
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 channels |
dual ranked | Double-sided DIMMs that provide two 64-bit banks.dual ranked |
dynamic RAM (DRAM) | The most common type of system memory, it requires refreshing every few milliseconds.dynamic RAM (DRAM) |
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.ECC (error-correcting code) |
EDO (extended data out) | A type of outdated RAM that was faster than conventional RAM because it eliminated the delay before it issued the next memory address.EDO (extended data out) |
