Abstract: Embodiments of a row address cache circuit are disclosed that may allow the determination the number of times a row address is used to access a dynamic memory. The row address cache circuit may include a memory, first and second pluralities of counters, and a control circuit. The control circuit may be configured to receive a row address and store the row address in an entry of the memory when the row address has not been previously stored. When the row address has been previously stored in an entry of the memory, the control circuit may be configured to change a value of a counter of the first plurality of counters corresponding the entry. The control circuit may be further configured to change a value of each counter of the second plurality of counters after a pre-determined time interval has elapsed, and initiate a refresh of the dynamic memory.

Abstract: According to an embodiment of the invention, an approach is provided for estimating how a particular user would rate a particular item from a plurality of items. The approach is applicable to any type of items, including rental items such as movies, music and games, and the invention is not limited to any particular type of item. One or more items from the plurality of items that have ratings similar to the particular item are identified. One or more other users are identified that have given ratings to the one or more items that are substantially similar to ratings given by the particular user to the one or more items. An estimation is made of how the particular user would rate the particular item based upon ratings for the particular item given by the one or more other users.

Abstract: An “inventory free” approach for managing rental items across a plurality of distribution locations includes sending at least some rental items that are not needed by two or more distribution locations to a designated distribution location. Rental items sent to the designated distribution location may be permanently stored at the designated distribution location, returned to the distribution location from which they were sent, or sent to other distribution locations, depending upon where the rental items are needed. In situations where particular rental items are not currently needed by customers at a distribution location, but there is a high likelihood that the particular rental items will be needed by the customers within a specified time, the particular rental items may be maintained at the distribution location as “float” and not sent to the designated distribution location. The float is re-processed as returned rental items prior to being again rented to customers.
