Memory Flashcards
1
Q
Parity Checking
A
A rudimentary error-checking scheme that offers no error correction.
2
Q
SIMM
A
Single Inline Memory Module
3
Q
DIMM
A
Double Inline Memory Module
4
Q
ECC
A
Error-correcting Code
5
Q
Single-Channel Memory
A
- memory controllers access data in chunks of the same size as the system data bus.
- This can create a bottle neck if the CPU and memory itself operate faster than the conduit between them.
6
Q
Dual-Channel Memory
A
- A memory controller coordinates two memory banks to work as a synchronized set during communication with the CPU
7
Q
Triple-Channel Memory
A
- Demands the coordination of three memory modules at a time.
8
Q
DRAM
A
Dynamic Random Access Memory
- Requires a constant refresh signal to keep the information that was written
9
Q
SRAM
A
Static Random Access Memory
- Doesn’t require refresh
- More expensive than DRAM
- Typically used for cache memory
10
Q
ROM
A
Read-only Memory
11
Q
PROM
A
Programmable ROM
12
Q
EPROM
A
Erasable/Programmable ROM
13
Q
SODIMM
A
Small Outline Dual Inline Memory Module
- Typically used in laptops
14
Q
Most popular memory module form factors
A
DIMM and SODIMM
