Non-volatile memory used as a re-writable, general purpose mass storage device for the switch. Information stored on the flash file my include bootable code images, configuration files, call record information, etc. Switch software supports user-initiated reading/writing from/to the flash (via TFTP protocol), allowing file backup/restore operations to a remote server.
EEPROM + EPROM
Programmable memory that is for system storage load and is used in the Integrated Boot Device (IBD).
A non-volatile programmable semiconductor memory product. Flash devices retain the contents of their memory when the power is turned off.
Flexible Architecture for SHared memory
FLASH is a type of ROM memory. It is more specifically a special type of EEPROM, but can only be erased in large blocks instead of one byte at a time. FLASH is cheaper than conventional EEPROM, and forms the bulk of memory on the HCS12. It is often used to hold executable code since such code does not change during regular program execution. As an example, D-Bug12 resides in the FLASH memory of the HCS12.
(EPROM): FLASH is erasable and reprogrammable non-volatile memory. Flash provides a better solution than regular EEPROM when there is a requirement for large amounts of non-volatile program memory. It is both faster and permits more erase/write cycles than EEPROM.
Flash memory is similar to RAM. It has one significant advantage: it does not lose its contents when power is lost; it has two main disadvantages: it is slower, and it eventually wears out. Flash memory is frequently found in PCMCIA cards.
to write over EPROM memory. Usually the content of this memory is unchanged when a device is turned on and off. On MR, this is usually used to denote "flashing" new firmware onto your player. [more...
Flash is electrically erasable and programmable in its application, but can only be erased/programmed by sectors (group of bytes) or the entire chip.
Programmable NVRAM memory that maintains its contents without power.
a type of semiconductor memory device that retains stored data even with the power off.
Erasable, reprogrammable Read Only Memory (ROM)
is a densely packable, relatively inexpensive type of nonvolatile memory, which can be modified electrically, often while in a circuit. Flash architecture generally assumes that it will be read often but seldom written to.
A type of memory - used in cellphones, iPods, etc. Nothing to do with flashiness. The original use of 'flash' memory - used in bios chips and other such techie things - was as a small, solid-state store of instructions that was permanent (ie not like RAM, where the stored data goes when the power is turned off), but which could be altered by updating it, aka to 'flash' it. So when people update their PC's bios, or alter the instruction set on a PC DVD drive to disable the region encoding, they still talk about 'flashing' it.
A type of non-volatile media that may allow byte read and write access, but requires the media to be erased before it is written. In addition, erase operations are required to be performed on a block of contiguous bytes.
A type of non-volatile memory that can be written much faster than EEPROM memory. Although usually written in all capital letters, FLASH is not an acronym, but rather refers to the fact that the memory can be bulk erased (that is, electronically "flashed" as PROM memory of yore was flashed with UV light).
A small, non-volatile memory. Non-volatile means that the memory keeps its data even when power to the computer is turned off. Some digital cameras use flash memory to store pictures. Not to be confused with ordinary camera flash, or a sudden realization. (giga): Short for 1,000,000,000 or 1,073,741,824. For network speeds, it means 1,000,000,000 - a gigabit Ethernet connection can send or receive 1,000,000,000 bits per second. For memory it means 1,073,741,824 - each gigabyte of memory is 1,073,741,824 bytes. Gigabyte is abbreviated GB.
a type of EEPROM where data is erased in blocks. The name Flash comes from the rapid block erase operation. Flash memory requires only one transistor per memory cell versus two transistors per memory cell for EEPROMs making Flash less expensive to produce. Flash is the most popular form of nonvolatile semiconductor memory available today.
A type of computer memory that can be rewritten and stores data without power.
Nonvolatile programmable technology, an alternative to Electrically-Erasable Programmable Read-Only Memory (EEPROM) technology. The memory content can be erased by an electrical signal. This allows in-system programmability and eliminates the need for ultraviolet light and quartz windows in the package.
typically used in credit card style removable storage devices such as digital cameras. Data stored in Flash is non-volatile and will not be lost when power is turned off.
1. Flash memory is a very common form of storage, especially for music and image files (like MP3 players and digital cameras). Flash memory is based on technology similar to RAM (solid state memory) with the crucial difference that flash memory retains its data even in the absence of power. 2. Flash is a scripting language used for dynamic applications and media, especially on the Internet. The latest version (as of January 2006) is version 8.
Memory device that takes the place of ROM or EPROM but that can be written to. Does not lose the contents of memory when the power is switched off.
