Updated this information with examples of the types of Read-write memory, and added history for the first commercial drive sold and the innovation of modern technologies. |

The term might also refer to memory locations having both read and write permissions. In modern computer systems using [[memory segmentation]], each segment has a length and set of permissions (for example, ''read'', ''write'', ''execute'') associated with it.
'''Types'''
Read-write memory is composed of either [[Volatile memory|volatile]] or [[Non-volatile memory|non-volatile]] types of storage. A computer holds many types of storage that can Read-write memory and be in many different physical sizes and forms. Typically read-write speeds are limited to its [[Bandwidth (computing)|bandwidth]] or have mechanical limitations of either rotation speeds and arm movement delays for storage types such as [[Cloud storage|Cloud Storage]], [[Hard disk drive|Hard Disk Drive]] or [[CD-RW|CD-RWs]], [[DVD recordable|DVD-RWs]], [[SD card|SD cards]], [[Solid-state drive|Solid State Drive]], [[Static random-access memory|SRAM]], and [[Dynamic random-access memory|DRAM]], or other [[Integrated circuit|integrated circuitry]].<ref>{{Cite web|title=Reading: Random Access Memory {{!}} Introduction to Computer Applications and Concepts|url=https://courses.lumenlearning.com/zeliite115/chapter/reading-random-access-memory/|access-date=2020-11-17|website=courses.lumenlearning.com}}</ref>
'''History'''
San Francisco in 1956, [[IBM]] was the first company to develop and sell the first commercial drive [[Hard disk drive|Hard Disk Drive(HDD)]] the drive was the Model 350 disk storage unit, which was 3.75 Megabytes of data storage capacity and had fifty 24-inch diameter disks stacked on a spindle and sold to [[Crown Zellerbach|Zellerbach paper]].<ref>{{Cite web|title=1956: First commercial hard disk drive shipped {{!}} The Storage Engine {{!}} Computer History Museum|url=https://www.computerhistory.org/storageengine/first-commercial-hard-disk-drive-shipped/|access-date=2020-11-17|website=www.computerhistory.org}}</ref>
Years of development have taken place since, and the development of read-write memory is larger in capacity and smaller in size. Today, you can store capacities of multiple [[Terabyte|terabytes]] of storage.
