20160004644 | Storage Controller and Method for Managing Modified Data Flush Operations From a Cache - A storage controller maintaining a cache manages modified data flush operations. A set-associative map or relationship between individual cache lines in the cache and a corresponding portion of the host managed or source data store is generated in such a way that a quotient can be used to identify modified data in the cache in the order of the source data's logical block addresses. The storage controller uses a collision bitmap, a dirty bit map and a flush table when flushing data from the cache. The storage controller selects a quotient and identifies modified cache lines in the cache identified by the quotient. As long as the quotient remains the same, the storage controller flushes or transfers the modified cache lines to the data store. Otherwise, when the quotient is not the same, the data in the cache is skipped. A linked list is used to traverse skipped cache lines. | 01-07-2016 |
20160026579 | Storage Controller and Method for Managing Metadata Operations in a Cache - A cache controller having a cache supported by a non-volatile memory element manages metadata operations by defining a mathematical relationship between a cache line in a data store exposed to a host system and a location identifier associated with an instance of the cache line in the non-volatile memory. The cache controller maintains most recently used bit maps identifying data in the cache, as well as a data characteristic bit map identifying data that has changed since it was added to the cache. The cache controller maintains a most recently used bit map to replace the recently map at an appropriate time and a fresh bitmap tracks the most recently used bit map. The cache controller uses a collision bitmap, an imposter index and a quotient to modify cache lines stored in the non-volatile memory element. | 01-28-2016 |

20110313830 | SYSTEM AND METHOD FOR TARGETING TRANSACTION ACCOUNT PRODUCT HOLDERS TO RECEIVE UPGRADED TRANSACTION ACCOUNT PRODUCTS - Utilization of information in a closed loop data system further augments modeling while at the same time enabling customization of offers based on spend patterns. Data mining techniques are leveraged to identify rules to determine higher response rate populations. These rules are referred to herein as “triggers,” in that the presence of particular attributes will trigger a cardholder as being more likely to respond to a particular offer. The benefit yielded by this approach is a greater acceptance rate to an offer provided by a transactional account company. To identify the triggers, records of cardmembers who already utilize a given product are analyzed to determine their spend patterns. The spend histories of customers who are eligible to use the product are analyzed according to the identified triggers. Customers whose spend patterns most closely correspond to the triggers are then targeted with offers for the given product. | 12-22-2011 |
