NVRAM (Non –Volatile Random-Access Memory ) is a memory chip that stores data within an electronic circuit. NVRAM is able to store data even when the power is turned off. This is unlike RAM and DRAM which lose memory when there is no power.
NVRAM memory is ideal for circuits that require a quick start up time as they are quick at reading and writing. However, they are not always suitable for main memory usage, due to limited memory sizes and power consumption. NVRAM is battery-back which, at some point, will need replacing.
These devices come in a semiconductor package. Package types include SIPP (single inline pin package), DIP (dual inline package), CERDIP (ceramic dual inline package) and PDIP (plastic inline package)
NVRAM memory is used in any device that requires settings to be stored, such as the date and time. This includes:
