Flash Memory

A solid-state, nonvolatile, rewritable memory that functions like a combination of RAM and hard disk. Flash memory is durable, operates at low voltages, and retains data when power is off. Flash memory cards are used in digital cameras, cell phones, printers, handheld computers, pagers, and audio recorders.

The size, configuration, and other specifications used to describe hardware. Examples of memory form factors are: SIMM, DIMM, RIMM, 30-pin, 72-pin, and 168-pin.

A process using the command format that will erase all data on a removable floppy or hard disk.

Approximately 1 billion bits, or exactly 1 bit x 1,024³ (1,073,741,824) bits.

Approximately 1 billion bytes, or exactly 1 byte x 1,024³ (1,073,741,824) bytes.

(Integrated Circuit) - An electronic circuit on a semiconductor chip. The circuit includes components and connectors. A semiconductor chip is usually molded in a plastic or ceramic case and has external connector pins.

Approximately one thousand bits, or exactly 1 bit x 2¹⁰ (1,024) bits.

Approximately one thousand bytes, or exactly 1 byte x 2¹⁰ (1,024) bytes.

(L1) - Also known as primary cache, L1 Cache is a small amount of high-speed memory that resides on or very close to the processor. L1 Cache supplies the processor with the most frequently requested data and instructions.

(L2) - Also known as secondary cache, L2 Cache is a small amount of high-speed memory close to the CPU and usually on the motherboard. L2 Cache supplies the processor with the most frequently requested data and instructions. Depending on the motherboard, Level 2 cache may be upgraded.

Approximately one million bits, or exactly 1 bit x 1,024² (1,048,576) bits.

Approximately one million bytes, or exactly 1 byte x 1,024² (1,048,576) bytes.

A computer's random-access memory. Memory temporarily holds data and instructions for the CPU. See RAM.

The bus that runs from the CPU to the memory expansion slots.

Also known as the logic board, main board, or computer board, the motherboard is the computer's main board and in most cases holds all CPU, memory, and I/O functions or has expansion slots for them.

(ns) - One billionth of a second. Memory data access times are in nanoseconds. For example, memory access times for typical 30- and 72-pin SIMM modules range from 60 to 100 nanoseconds.

An operating system is a program that manages all other programs on the computer. It is the main program that uses the GUI to allow for interaction of all other programs.

(Peripheral Component Interconnect) - A peripheral bus that can send 32 or 64 bits of data simultaneously. PCI offers plug-and-play capability.

A technique in which memory loads the requested memory contents into a small cache composed of SRAM, then immediately begins fetching the next memory contents. This creates a two-stage pipeline, where data is read from or written to SRAM in one stage, and data is read from or written to memory in the other stage.
