Read-write memory

From Wikipedia, the free encyclopedia

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 ROM or "read-only memory" and distinct from EEPROM).[1] The related term RAM (for "random access memory") means something different; it refers to memory that can access any memory location in a constant amount of time.[2]

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.
