serial-access memory (SAM)
(1) A memory (or serial port in a multiport memory) in which data is accessed sequentially and the time for access depends on the location of the data desired. In a multiport memory, this term refers to that portion of the device that is related to the serial-access port and its associated functions.
(2) A memory in which data can be accessed only in a predetermined sequence. (Adapted from IEC 748‑2.)
