Click here for a printable version of this file

SECTION I - CLASS DEFINITION

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.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

A. This class includes static memory systems wherein the information stored in the memory element has electrical, magnetic, or optical properties. This class excludes mechanical or fluidic type storage of information, e.g., card files, cams, levels, or fluids, etc. This class also excludes the storage of noninformation, e.g., energy, basic signal control means, etc.

B. Processes for the manufacturing of storage elements are not classified within this class. See appropriate classes in References To Other Classes, below.

C. Storage Signals, per se, are not classified herein. (See appropriate classes in the References To Other Classes, below.)

D. Circuits not specific to storage and retrieval which may constitute subcombinations of such apparatus are classified in the appropriate class for such circuits, e.g., photosensitive devices. See References to Other Classes, below.

E. The combination of the subject matter of this class and an art environment is classified with the art environment.

F. For static storage and retrieval systems, devices, and arrangements found in other classes: see appropriate classes in Reference To Other Classes, below.

G. The organization of this class can be found in Subclass References to the Current Class, below.
