DEFINITION

Classification: 711/101

Specific memory composition:

(under subclass 100) Subject matter wherein control of the memory or the accessing thereof is adapted to the type of memory being accessed.

(1) Note. Structures and particulars of the memory device itself are classified in the relevant device class.

(2) Note. Subject matter included herein is directed to the specifics of accessing technique employed to access and control the memory by computers, digital data processing systems, processors, or other users.

(3) Note. The nature of data stored in a memory (i.e., the information) does not make the memory "specific" within the context of this and its indented subclasses (e.g., video or image data, printer buffer, control data memory, etc.).

(4) Note. Accessing and controlling of a multiport memory, per se, are classified elsewhere in this class. See the SEARCH THIS CLASS, SUBCLASS notes below.
