A solid-state drive (SSD) provides secondary storage for relatively complex systems including personal computers, embedded systems, portable devices, large servers and network-attached storage (NAS). To satisfy such a wide range of uses, SSDs are produced with various features, capacities, interfaces and physical sizes and layouts.
A solid-state drive (SSD) is a solid-state storage device. It provides persistent data storage using no moving parts. It is sometimes called semiconductor storage device or solid-state device. It is also called solid-state disk because it is frequently interfaced to a host system in the same manner as a hard disk drive (HDD). [1] [2]
In the late 1980s IBM had built DRAMs using a dual-edge clocking feature and presented their results at the International Solid-State Circuits Convention in 1990. [ 6 ] [ 7 ] Samsung demonstrated the first DDR memory prototype in 1997, [ 1 ] and released the first commercial DDR SDRAM chip (64 Mbit ) in June 1998, [ 8 ] [ 2 ] [ 3 ] followed ...
Gutmann method. The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files. Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
In the list those manufacturers that also produce hard disk drives or flash memory are identified. Additionally, the type of memory used in their solid-state drives is noted. This list does not include the manufacturers of specific components of SSDs, such as flash memory controllers. [1]
The same year, the concept of solid-state memory on an integrated circuit (IC) chip was proposed by applications engineer Bob Norman at Fairchild Semiconductor. [10] The first single-chip memory IC was the BJT 16-bit IBM SP95 fabricated in December 1965, engineered by Paul Castrucci.

Memory refresh is a process of periodically reading information from an area of computer memory and immediately rewriting the read information to the same area without modification, for the purpose of preserving the information. [ 1] Memory refresh is a background maintenance process required during the operation of semiconductor dynamic random ...
