random-access memory (RAM)

(1) A memory in which access to all storage data can be achieved in essentially the same time, independent of the location. In a multiport memory, this term refers to that portion of the array that contains the memory cell array and its drivers, sense amplifiers, control circuitry, and the circuitry associated with the normal random-access data port.

(2) A memory that permits access to any of its address locations in any desired sequence with similar access time to each location. (Adapted from IEC 748‑2.)

NOTE The term "random-access memory", as commonly used, denotes a read/write memory with unlimited data rewrite capability and similar read and write times.
