A rarely used and improved on EDO found on some 72-pin SIMMs or 168-pin DIMMs.
What is Burst EDO (BEDO)
100
The memory a processor addresses at one time and is 64 bits wide.
What is Memory bank
100
A type of out dated RAM that was faster than conventional RAM because it eliminated the delay before it issued the next memory address.
What is EDO (extended data out)
100
The most common type of system memory, it requires refreshing every few milliseconds
What is dynamic RAM (DRAM)
100
A feature of memory that reflects the number of clock cycles that pass while data is written to memory.
What is CAS Latency
200
A motherboard feature that improves memory performance by providing two 64-bit channels between memory and the chipset. DDR and DDR2 memory can use this.
What is Dual channels
200
A chipset feature on a motherboard that checks the integrity of data stored on DIMMs or RIMMs and can fix single-bit errors in a byte. More advanced schemas can detect, but not fix double-bit errors in a byte.
What is ECC (Error-correcting code)
200
A smaller version of a DIMM used on laptops.
What is SO-DIMM (small outline DIMMS)
200
An error the occurs when the number of 1s in the byte is not in agreement with expected number.
What is Parity error
200
A type of memory technology used on DIMMs that run at twice the speed of the system clock.
What is Double data rate SDRAM
300
Chips that have been used and returned to the factory, marked again, and resold. The surface may be dull or scratched.
What is Re-marked chips
300
A DIMM with memory chips installed on one side of the module.
What is Single-sided
300
An outdated type of DRAM with 72 or 30 pins.
What is SIMM (single inline memory module)
300
A DIMM in which the memory controller can only access one DIMM at a time.
What is Single channel
300
Single-sided DIMMs providing only 64-bit bank.
What is Single ranked
400
Three improvements to SDRAM.
What is DDR, DDR2, DDR3
400
Double-sided DIMMs that provide two 64-bit banks
What is Dual ranked
400
A placeholder RIMM module that provides continuity so that every RIMM slot is filled.
What is C-RIMM
400
Accessing three DIMMs at the same time.
What is Triple channels
400
An outdated type of DRAM with 184 pins.
What is RIMM
500
An error-checking scheme in which a ninth bit is added. The value of the bit is either 0 or 1 to provide an even number of ones for even bit and an odd number of ones for an odd bit.
What is Parity
500
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.
What is General Protection Fault (GPF)
500
The first DIMM to run synchronized with the system clock. It has two notches, and uses 168 pins.
What is Synchronous DRAM (SDRAM)
500
A memory technology that uses a narrow network-type system bus. Memory is stored on a RIMM module.
What is Direct Rambus DRAM
500
Can be used with 30-pin or 72-pin SIMMs or some really old 168-pin DIMMs.
