|
bank
|
An area on the motherboard that contains slots for memory modules (typically labeled bank 0, 1, 2, and 3).
|
|
|
burst EDO (BEDO)
|
A refined version of EDO memory that significantly improved access time over EDO. BEDO was not widely used because Intel chose not to support it. BEDO memory is stored on 168-pin DIMM modules.
|
|
|
cache on a stick (COAST)
|
Memory modules that hold memory used as a memory cache. See memory cache.
|
|
|
CAS Latency (CL)
|
A feature of memory that reflects the number of clock cycles that pass while data is written to memory.
|
|
|
C-RIMM (Continuity RIMM)
|
A placeholder RIMM module that provides continuity so that every RIMM slot is filled.
|
|
|
DDR2 SDRAM
|
A version of SDRAM that is faster than DDR and uses less power.
|
|
|
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 RDRAM.
|
|
|
Direct RDRAM
|
Another term for Direct Rambus DRAM.
|
|
|
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.
|
|
|
dual channel
|
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.
|
|
|
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A type of outdated RAM that was faster than conventional RAM because it eliminated the delay before it issued the next memory address.
|
|
|
General Protection Fault (GPF)
|
A Windows error that occurs when a program attempts to access a memory address that is not available or is no longer assigned to it.
|
|
|
nonparity memory
|
Eight-bit memory without error checking. A SIMM part number with a 32 in it (4 x 8 bits) is nonparity.
|
|
|
parity
|
An error-checking scheme in which a ninth, or “parity,” bit is added. The value of the parity bit is set to either 0 or 1 to provide an even number of ones for even parity and an odd number of ones for odd parity.
|
|
|
parity error
|
An error that occurs when the number of 1s in the byte is not in agreement with the expected number.
|
|
|
parity memory
|
Nine-bit memory in which the ninth bit is used for error checking. A SIMM part number with a 36 in it (4 x 9 bits) is parity. Older PCs almost always use parity chips.
|
|
|
RAS Latency
|
feature of memory that reflects he number of clock cycles that pass while data is written to memory.
|
|
|
RDRAM
|
Another term for Direct Rambus DRAM.
|
|
|
refresh
|
As applied to monitors, the number of times in one second an electronic beam can fill the screen with lines from top to bottom. Also called vertical scan rate.
|
|
|
re-marked chips
|
Chips that have been used and returned to the factory, marked again, and resold. The surface of the chips may be dull or scratched.
|
|
|
SDRAM II
|
Another term for Double Data Rate SDRAM.
|
|
|
synchronous DRAM (SDRAM)
|
A type of memory stored on DIMMs that runs in sync with the system clock, running at the same speed as the motherboard.
|
|
|
SyncLink DRAM (SLDRAM)
|
A type of DRAM developed by a consortium of 12 DRAM manufacturers. It improved on regular SDRAM but is now obsolete.
