serial-access memory
computer science
Also known as: sequential-access memory
Quick Summary
Serial-access memory is a type of computer memory where data must be accessed in a specific sequence, unlike random-access memory (RAM) where data can be accessed directly by the CPU. Magnetic tape is an example of serial-access memory, primarily used for archiving data due to its slower access times compared to magnetic disks. This sequential retrieval process means that to reach a specific piece of data, all preceding data must be read first.1
