Programmable Read-Only Memory. Can't be erased or re-written

Erasable Programmable Read-Only Memory. can be erased with exposure to UV light-special equipment.

Electrically Erasable Programmable Read-Only Memory. Can be erased and re-written without being removed from the computer.

Dynamic RAM. Must be constantly refreshed with pulses of electricity.

Static Ram. Cache memory, much faster, does not have to be refreshed as often.

Synchronous DRAM in sync with the memory bus.

The data path between the CPU and the main memory.

Double Data Rate SDRAM. Twice as fas as SDRAM.

Faster than DDR by decreasing noise and crosstalk between the signal wires.

Doubles clock rate of DDR2. Consumes less power and generates less heat than DDR2.

Memory chip developed to communicate at very high speed. Not commonly used.

PC2-5300, PTR 5333 MB/s, 667MHz

PC3-12800, PTR 12800 MB/s, 1600 MHz

Internal cache integrated into the CPU

External cache and was originally mounted on the motherboard near the CPU. Now integrated into the CPU.

Used on some high-end workstations and server CPUs.

Does not check for errors in memory.

Contains eight bits for data and one bit for error checking. The error-checking bit is called a parity bit.

Error Correction Code memory can detect multiple bit errors in memory and correct single bit errors in memory.

Peripheral Component Interconnect is a 32-bit or 64-bit expansion slot.

Advanced Graphics Port is a 32-bit expansion slot.

A serial bus expansion slot. x1, x4, x8, and x16 slots.

Industry Standard Architecture, an 8-bit or 16-bit expansion slot.

Extended Industry Standard Architecture. A 32-bit expansion slot.

Microchannel Architecture, an IBM-proprietary 32-bit expansion slot.
