NVFS
Overview
NVFS is a new standard in PDA memory, introduced by Palm in 2005. Until then, PDAs only had dynamic RAM that constantly require power to maintain their contents. This means if a device runs out of battery power completely, the contents of memory will be lost. It also drains the battery, even during standby, at a rate proportional to how much memory the device has -- this may be why no volatile memory PDA has ever shipped with more than 128Mb of memory.
NVFS, by comparison, uses non-volatile Flash RAM that does not need power to maintain contents.
