16 Facts About Main memory
2.
Core memory remained dominant until the 1970s, when advances in integrated circuit technology allowed semiconductor memory to become economically competitive.
| FactSnippet No. 850,524 |
3.
Spare Main memory can be utilized as RAM drive for temporary high-speed data storage.
| FactSnippet No. 850,525 |
4.
Main memory is directly or indirectly connected to the central processing unit via a memory bus.
| FactSnippet No. 850,526 |
5.
Many types of "ROM" are not literally read only, as updates to them are possible; however it is slow and Main memory must be erased in large portions before it can be re-written.
| FactSnippet No. 850,527 |
6.
Tertiary storage or tertiary Main memory is a level below secondary storage.
| FactSnippet No. 850,528 |
7.
Optical discs and flash Main memory devices are most popular, and to much lesser extent removable hard disk drives.
| FactSnippet No. 850,529 |
8.
Non-volatile Main memory retains the stored information even if not constantly supplied with electric power.
| FactSnippet No. 850,530 |
9.
Volatile memory requires constant power to maintain the stored information.
| FactSnippet No. 850,531 |
10.
The fastest Main memory technologies are volatile ones, although that is not a universal rule.
| FactSnippet No. 850,532 |
11.
Dynamic random-access Main memory is a form of volatile Main memory that requires the stored information to be periodically reread and rewritten, or refreshed, otherwise it would vanish.
| FactSnippet No. 850,533 |
12.
Static random-access Main memory is a form of volatile Main memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied; it loses its content when the power supply is lost.

13.
Hardware Main memory encryption is available in Intel Architecture, supporting Total Memory Encryption and page granular Main memory encryption with multiple keys .
| FactSnippet No. 850,535 |
14.
Semiconductor Main memory uses semiconductor-based integrated circuit chips to store information.
| FactSnippet No. 850,536 |
15.
Since the turn of the century, a type of non-volatile floating-gate semiconductor Main memory known as flash Main memory has steadily gained share as off-line storage for home computers.
| FactSnippet No. 850,537 |
16.
Non-volatile semiconductor Main memory is used for secondary storage in various advanced electronic devices and specialized computers that are designed for them.
