non-volatile memory
(redirected from Non-volatility)

   Also found in: Wikipedia 0.02 sec.

non-volatile memory

Refers to memory chips that hold their content without power being applied. It may refer to chips that are not changeable, such as ROMs and PROMs, or to chips that can be rewritten many times such as flash memory. Being able to hold instructions and data without power is essential in a myriad of devices because AC power can fail and batteries become depleted. Rewritability is essential in many applications as well.

Although magnetic disks hold their content without power, they are more accurately called "storage devices," rather than non-volatile memory. See memory types for more details. See future memory chips.

appears well suited for certain mobile applications where speed, non-volatility and low power are all important, IBM researchers say.
nbsp;(DRAM), the high speed of Static RAM (SRAM), and the non-volatility of flash memory.
The new 4Mbit devices deliver 40% better access times, 4 to 8 times higher densities and increased system performance over their predecessors, enabling them to leapfrog alternative non-volatile memory technologies in traditional markets while offering key new benefits for emerging solid-state-drives (SSDs), hard disk drives and other new system memory architectures that require the speed of SRAM, density of DRAM and non-volatility of flash memory.
