nonvolatile memory
Computing term for memory that retains data without power, such as flash memory or ROM.
Nonvolatile memory retains data even when the power is turned off.
Volatile memory (e.g., RAM) loses data when power is removed, unlike nonvolatile memory.
Compound of 不 (non-), 揮発性 (volatility), and メモリ (memory). A direct technical translation of the English term.
