Publication number: 20150046658Abstract: A method and information processing system with improved cache organization is provided. Each register capable of accessing memory has associated metadata, which contains the tag, way, and line for a corresponding cache entry, along with a valid bit, allowing a memory access which hits a location in the cache to go directly to the cache's data array, avoiding the need to look up the address in the cache's tag array. When a cache line is evicted, any metadata referring to the line is marked as invalid. By reducing the number of tag lookups performed to access data in a cache's data array, the power that would otherwise be consumed by performing tag lookups is saved, thereby reducing power consumption of the information processing system, and the cache area needed to implement a cache having a desired level of performance may be reduced.Type: ApplicationFiled: August 8, 2013Publication date: February 12, 2015Applicant: FREESCALE SEMICONDUCTOR, INC.Inventor: Peter J.

Publication number: 20150046893Abstract: A technique for electromigration stress mitigation in interconnects of an integrated circuit design includes generating a maximal spanning tree of a directed graph, which represents an interconnect network of an integrated circuit design. A first point on the spanning tree having a lowest stress and a second point on the spanning tree having a highest stress are located. A maximum first stress between the first and second points is determined. In response to determining the maximum first stress between the first and second points is greater than a critical stress, a stub is added to the spanning tree at a node between the first and second points. The maximum first stress between the first and second points is re-determined subsequent to adding the stub.Type: ApplicationFiled: April 30, 2014Publication date: February 12, 2015Applicant: FREESCALE SEMICONDUCTOR, INC.Inventors: ERTUGRUL DEMIRCAN, MEHUL D.

Patent number: 8946862Abstract: Methods are provided for forming a device that includes merged vertical and lateral transistors with collector regions of a first conductivity type between upper and lower base regions of opposite conductivity type that are Ohmically coupled via intermediate regions of the same conductivity type and to the base contact. The emitter is provided in the upper base region and the collector contact is provided in outlying sinker regions extending to the thin collector regions and an underlying buried layer. As the collector voltage increases part of the thin collector regions become depleted of carriers from the top by the upper and from the bottom by the lower base regions. This clamps the collector regions' voltage well below the breakdown voltage of the PN junction formed between the buried layer and the lower base region. The gain and Early Voltage are increased and decoupled and a higher breakdown voltage is obtained.Type: GrantFiled: March 6, 2014Date of Patent: February 3, 2015Assignee: Freescale Semiconductor, Inc.Inventors: Xin Lin, Daniel J.
