FLASH Memory
FLexible Architecture for SHared Memory, non-volatile semiconductor memory with access time approximately that of EEPROM or EAPROM and density similar to that of an EPROM. Flash memory is generally limited to about 100,000 erase cycles. Usually packaged in PCMCIA for plugging into a laptop computer card slot......

Memory
A data storage structure in a computer that accepts binary information for storage in electrical, mechanical, or magnetic form, and retains the information for as long as needed. Selected data can be written, moved, displayed, copied, or erased. The variety of memory media includes: paper, magnetic, bubble, optical laser, and semiconductor memory. .....

Read-Only Memory (ROM)
A semiconductor memory whose data cannot be erased, or overwritten; it can only be accessed (read) for use by the CPU. The data in a ROM is of a permanent nature and is programmed by the ROM manufacturer. In many cases, its programmed information identifies the dedicated function of a computer. A ROM can also be in the physical form of a module (ta.....

Volatile memory
A memory whose contents are irretrievably lost when power is removed. If data in RAM must be saved after power shut-down, back-up in nonvolatile memory (magnetic disk, tape, or CD-R) is essential......

Cache
A special high-speed storage mechanism, either as a reserved section of main memory or an independent high-speed storage device. This high-speed buffer memory is similar to a Scratch pad memory, but has a larger capacity; it is located in the Central Processing Unit. A cache can also serve as a storage section between the CPU and a hard disk to spe.....

Bubble memory
A high-density memory medium upon which a magnetic film is grown on a gadolinium-gallium garnet substrate. A small permanent magnet is mounted inside its package, perpendicular to the surface of the substrate. When an external magnetic field is created with an external coil, magnetic "bubble" domains are formed on the internal magnetic film which r.....
