A Study about Non-Volatile Memories.pdf

This paper presents an upcoming
nonvolatile memories (NVM) overview. Non-volatile
memory devices are electrically programmable and
erasable to store charge in a location within the
device and to retain that charge when voltage supply
from the device is disconnected. The non-volatile
memory is typically a semiconductor memory
comprising thousands of individual transistors
configured on a substrate to form a matrix of rows
and columns of memory cells. Non-volatile memories
are used in digital computing devices for the storage
of data. In this paper we have given introduction
including a brief survey on upcoming NVM's such as
FeRAM, MRAM, CBRAM, PRAM, SONOS, RRAM,
Racetrack memory and NRAM. In future Nonvolatile
memory may eliminate the need for
comparatively slow forms of secondary storage
systems, which include hard disks.
