TLDR
In this paper, the write-back of data segments in the cache memory to the bulk memory for replacement purposes is accomplished in accordance with a least recently used algorithm while the writeback of written-to segments to the base memory without replacement is accomplished according to an age since first write algorithm.Abstract:
In a memory system having a cache memory and a bulk memory, write-back of data segments in the cache memory to the bulk memory for replacement purposes is accomplished in accordance with a least recently used algorithm while the write-back of written-to segments to the bulk memory without replacement is accomplished in accordance with an age since first write algorithm.read more

Multiprocessor digital data processing system
Steven J. Frank,Henry Burkhardt,Linda O. Lee,Nathan Goodman,Benson I. Margulies,Frederick D. Weber +5 more
TL;DR: In this paper, a multiprocessor digital data processing system comprises a plurality of processing cells (18A to 18R, 34A to 34F, 38A, 38B) arranged in a hierarchy of rings.
Patent
Disk meshing and flexible storage mapping with enhanced flexible caching
TL;DR: In this article, a hierarchical memory system is provided which includes a cache and long-term storage, in which an address of a requested data block is translated to a second addressing scheme, and is meshed, so that proximate data blocks are placed on different physical target disks within the longterm storage.
Patent
Solid state disk drive unit having on-board backup non-volatile memory
TL;DR: Disclosed as mentioned in this paper is a solid state disk drive, including a volatile, electronic RAM, memory and a non volatile, magnetic disk, which continuously saves unique data stored in the memory back to the disk.
Patent
Shared memory multiprocessor system and method of operation thereof
Steven J. Frank,Henry Burkhardt,Linda O. Lee,Nathan Goodman,Benson I. Margulies,Frederick D. Weber +5 more
TL;DR: In this article, a memory manager responds to selected data access requests by allocating, within the memory local to the requesting CPU, exclusive physical storage space for a data page associated with the requested subpage.
Patent
Disk storage system with write preservation during power failure
TL;DR: A disk storage system including means for assuring completion of data writes to a data storage disk upon failure of electrical power receives data write commands including data to be written to one or more storage disks as mentioned in this paper.

Patent
System for facilitating the copying back of data in disc and tape units of a memory hierarchial system
TL;DR: In this paper, a multi-level or hierarchial memory system for a multi processing system in which two or more processing units access the memory system has been proposed, with two types of memory units on each level with the exception of the lowest level.
Patent
Multi-processing system with a hierarchial memory having journaling and copyback
TL;DR: In this paper, a hierarchical memory system for multi-processing systems with two different types of memory units on each level is described, the data store and the copy back data store in each level are on two different power systems and transfers of the changes to the next lower level are done in the order in which the change entered in the copyback store with the oldest entry being the first to be copied back.
Patent
Instruction retry mechanism for a data processing system
TL;DR: In this paper, an instruction retry mechanism is proposed to enable a digital data processing system having main, buffer and local stores to restart and, in most cases, recover from an error or failure in the processor hardware associated with the buffer and the local stores.
Patent
Memory hierarchy system with journaling and copy back
Bruce A. Edson,Vincent A. Cordi +1 more
TL;DR: In this article, a hierarchical memory system has two memory units on each level, a data store and a copy back store, which contains all the changes that have been made in that data either by addition or modification.
Patent
Cache memory store in a processor of a data processing system
TL;DR: In this article, the cache store is operated in parallel to the request for data information from the main memory store and a successful retrieval from the cache cache store aborts the retrieval from a main memory.
