Question | Answer |
---|---|
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. |
memory bank | The memory a processor addresses at one time. Today's desktop and notebook processors use a memory bank that is 64 bits wide |
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. |
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. |
RIMM | A type of memory module developed by Rambus, Inc. |
SIMM (single inline memory module) | A miniature circuit board used in older computers to hold RAM. SIMMs holds 8, 16, 32, or 64 MB on a single module. |
Single channel | The memory controller on a motherboard that can access only one DIMM at a time. Compare to dual channel and triple channel. |
single ranked | DIMMs that provide only one 64-bit bank. All memory chips on the DIMM are accessed at the same time. Compare to dual ranked. |
single-sided | Memory chips embedded on only a single side of a DIMM. |
SO-DIMM (small outline DIMM) | A type of memory module used in notebook computers that uses DIMM technology. A DDR3 SO-DIMM has 204 pins. A DDR2 or DDR SO-DIMM has 200 pins. Older, outdated SO-DIMMs can have 72 pins or 144 pins. |
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. |
triple channels | When the memory controller accesses three DIMMs at the same time. DDR3 DIMMs support triple channeling. |
