This is the generic class for apparatus or corresponding processes for the static storage and retrieval of information. For classification herein, the storage system
must be (1) static, (2) a singular storage element or plural elements of the same type, (3) addressable.
(1) Note. Static storage and retrieval of information within this class means that relative motion is not required between the storage element and the source, receiver, or transducer. For dynamic storage and retrieval or magnetic information, see References to Other Classes, below.
(2) Note. The storage elements within this class are plural elements of the same type which may store one or more bits of information per element.
(3) Note. The storage system must be addressable, that is, there must be an inherent means for writing information into a memory and a means for reading the same information from the memory. For switching systems, selective systems, card readers, and recorders, see References to Other Classes, below. Static memory systems involving data processing techniques are classified elsewhere.
