Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain saved data even after power is eliminated. In distinction, volatile memory needs fixed power with a view to retain information. Non-risky memory typically refers to storage in memory chips, which retailer knowledge in floating-gate memory cells consisting of floating-gate MOSFETs (steel-oxide-semiconductor discipline-impact transistors), together with flash memory storage resembling NAND flash and strong-state drives (SSD). Different examples of non-risky memory include read-solely memory (ROM), EPROM (erasable programmable ROM) and EEPROM (electrically erasable programmable ROM), ferroelectric RAM, most kinds of computer information storage devices (e.g. disk storage, onerous disk drives, optical discs, floppy disks, and magnetic tape), and early pc storage methods comparable to punched tape and playing cards. Non-unstable memory is often used for the task of secondary storage or lengthy-term persistent storage. RAM is lost. However, most forms of non-volatile memory have limitations that make them unsuitable for use as primary storage. Usually, non-risky memory costs extra, gives lower performance, or has a limited lifetime compared to risky random entry memory.

Typically speaking, electrically addressed programs are expensive, and have limited capability, but are quick, whereas mechanically addressed methods price less per bit, but are slower. Electrically addressed semiconductor non-risky recollections could be categorized in line with their write mechanism. Mask ROMs are manufacturing facility programmable solely and usually used for large-volume products which aren’t required to be updated after the memory system is manufactured. Programmable learn-only memory (PROM) will be altered once after the Memory Wave Program gadget is manufactured using a PROM programmer. Programming is usually done before the system is installed in its goal system, usually an embedded system. The programming is permanent, and further changes require the alternative of the system. Knowledge is stored by physically altering (burning) storage sites within the machine. An EPROM is an erasable ROM that can be modified more than once. Nonetheless, writing new information to an EPROM requires a particular programmer circuit. EPROMs have a quartz window that allows them to be erased with ultraviolet mild, however the entire device is cleared at one time.

A one-time programmable (OTP) system may be carried out using an EPROM chip with out the quartz window
