QuestionAnswer
Burst EDO (BEDO) A refined version of burst EDO memory that significantly improved access time over EDO.
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. CAS stands for Column Access Strobes.
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.
DDR3 A version of SDRAM that is faster than DDR3 memory and that can use triple channals.
Direct Rambus DRAM A memory technology by Rambus and Intel that uses a narrow network type system bus. Memory is stored a RIMM module.
Double Data Rate SDRAM A type of memory technolgy used on double data DIMMs that runs at twice the speed of the system clock.
DDR SDRAM A type of memory technolgy used on DIMMs that runs at twice the speed of the system clock. Aslo called DDR SDRAM or Double Data Rate SDRAM.
double-sided A DIMM feature whereby memory chips are installed on double sided of a DIMM.
dual channels A motherboard feature that improves memory performance by providing two 64 bit dual channels between memory and the chipset.
dual ranked Double sided DIMMs that provide two 64 bit banks.The memory controller access first one bank and then the other. Dual ranked DIMMs do not perform as well as single ranked DIMMs.
dynamic RAM (DRAM) The most common type of system dynamic RAM memory, it requires refreshing every few milliseconds.
ECC (error-correcting code) A chipset feature on a motherboard that checks the ECC integrity of data stored on DIMMs or RIMMs and can correct single 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EDO (extended data out) A type of outdated RAM that was faster than conventional RAM because it eliminated the delay EDO before it issued the next memory address.
FPM (fast page memory) An outdated memory mode used before the introduction of EDO memory. FPM improved on earlier memory types by sending the row address just once for many accesses to memory near that row.
