non-volatile RAM (NVRAM)

Non-Volatile RAMs (NVRAM) are non-volatile random access RAMs that continue to store data even after the supply voltage is switched off. An NVRAM uses an uninterruptible power supply( UPS), rechargeable batteries, batteries or flash memory technology in the event of a power failure. NCRAMs include the ferroelectric FeRAMs, magneto-resistive RAMs( MRAM) and phase change RAMs( PRAM).
