Memory system with multiple open rows per bank
A dynamic random access memory (DRAM) component (e.g., module or integrated circuit) can be configured to have multiple rows in the same bank open concurrently. The controller of the component divides the address space of the banks into segments based on row address ranges. These row address ranges do not necessarily correspond to row address ranges of the bank's subarrays (a.k.a. memory array tiles—MATs). When a command is sent to open a row, the controller marks a plurality of the segments as blocked. The controller thereby tracks address ranges in a bank where it will not open a second row unless and until the first row is closed. The memory component may store information about which, and how many, segments should be blocked in response to opening a row. This information may be read by the controller during initialization. |

Controlling use of negative features in a matching operation
A computer-implemented technique is described herein for assisting an administrative user in generating negative feature information. The negative feature information, which includes a list of negative features (e.g., negative keywords), defines when queries submitted by end users are expressly disqualified as matching one or more parts of an identified web resource. The technique then automatically assesses the manner in which the negative feature information conflicts with matching between the queries submitted by end users and positive trigger information associated with the web resource, to provide conflict output information. The technique then modifies the negative feature information based on the conflict output information, e.g., by eliminating one or more negative keywords that contribute to conflicts. |

Linking a transaction with a merchant to an interaction with an augmented reality advertisement
Customers receive an incentive with use of an installed cellphone app to image an AR-bearing ad. Matches between data from the customer's accounts for each merchant are compared to the data in association with the customer's logical identifier for their cellphone, and particularly with each incidence of a rendering on their display screen of an AR view of a product advertisement containing the AR-triggering symbol to initiate the corresponding AR enhanced view of the ad. In conjunction with chronological time stamping of occurrences, a likelihood is derived that the customer's viewing of the AR enhanced product advertisement influenced the potential customer's subsequent purchase of the corresponding advertised product as evidenced within the potential customer's rich transactional data from the customer's debit and/or credit accounts. The certainty of each match is determined to further initiate the merchant's incentive to the customer which may be the merchant's donation to a community program. |
