This publication describes a simple, hardware implemented means for private or common sharing, or not sharing of data segments in a hybrid memory system. In virtual memory systems, it is desirable to share data segments in some way, either privately or globally. The typical type of sharing is global sharing of COMMON Segments in the MVS operating system. IBM Virtual Machine Facility/370 (VM/370) and, to some extent, TSS (Time Sharing System) provide for private sharing of segments at the segment level. The future operating system MVS/E, while fundamentally providing global "Common" as the main means for sharing, will also incorporate a means to be compatible with VM/370 and TSS. Thus, private as well as common and no sharing of segments at the segment level are desirable and must be provided in a hybrid approach.
