'''Read-write memory''' is a type of [[computer memory]] that may be relatively easily written to as well as read from, that is, using electrical signalling normally associated with running a software, and without any other physical processes (unlike [[Read-only memory|ROM]] or "read-only memory" and distinct from [[EEPROM]]).<ref>{{cite web |url=https://www.jedec.org/standards-documents/dictionary/terms/readwrite-memory |title=JEDEC: read/write memory |website=JEDEC |accessdate=7 March 2017}}</ref> The related term [[RAM]] (for "random access memory") means something isssdifferent; it refers to memory that can access any memory ___location in a constant amount of time.<ref>{{cite |url=https://www.jedec.org/standards-documents/dictionary/terms/random-access-memory-ram |website=JEDEC |title=JEDEC: random-access memory |accessdate=7 March 2017}}</ref>

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.
