NVRAM is ‘Non-Volatile Random Access Memory.’ It is a type of Random Access Memory that retains data after the host device’s power is turned off or has suffered an inadvertent power loss.
The Greenwich Instruments NVRAM devices retain critical data, at this point of power failure, by using an alternative source of power in the form of its self-contained, internal, lithium battery. This Non-volatile Static RAM is often used to store computer hardware settings or data that needs to be maintained when the computer is shut down.
Power down is very fast, essential for data integrity. The power down circuit is referenced and triggered at 4.5V. Data is retained in less than 15microseconds, much faster than power failure conditions.
