In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The sometimes conflicting needs to maintain data integrity and system performance are balanced by deferring execution of some of the corrective action when the memory system has other high priority operations to perform. In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase.

Described herein is a system for executing distributed transactions. A coordinator and one or more participants cooperate to execute a distributed transaction, the distributed transaction including for each participant a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. Before each participant commits the transaction, the participants determine that the coordinator has committed the transaction. The coordinator commits the transaction after receiving acknowledgment from all the participants that they will commit the transaction. To determine whether the coordinator has committed the transaction, a participant transmits a message to the coordinator to acknowledge that it will commit the distributed transaction. The participant commits its respective transaction if it receives an acknowledgement from the coordinator. For the particular transaction being executed by a participant, the participant prevents other transactions from modifying a data item affected by the particular transaction. The participant will prevent such modifications until termination criteria for the particular transaction is satisfied, in which case the participant terminates the transaction.

The present invention provides a gaming device, wherein the game requires the same average investment from a player to win an award, including a jackpot award, regardless of the amount that the player bets at any one time. The award can be unchanging, e.g., $10,000, each time a player plays the gaming device. The award can also vary such as with a progressive jackpot, i.e., the jackpot builds until a player “hits” the jackpot. The game enables the average investment necessary to win the jackpot to be uniform by varying the odds of winning the jackpot as the player's bet varies. That is, a player betting less money needs to play the game more times, on average, to win the jackpot. Likewise, a player betting more money needs to play the game less times, on average, to win the jackpot. The average overall bet or investment thus remains constant despite the player's betting habits or betting ability.

The content metadata directory system connects consumers of identified content to managed metadata databases and other digital resources. The system manages links between identifiers in content objects and metadata sources. It supports a variety of different type of content identifiers and allows for overlap among different content identification schemes. One method of associating a content object with metadata uses a combination of a content identifier and a bounding identifier to enable handling of disparate sets of content identifiers for content objects with potentially conflicting content identifiers. The method receives a content identifier for a content object from among a set of content identifiers and provides a unique bounding identifier for the set of content identifiers. This unique bounding identifier is used in combination with the content identifier to form a globally unique identifier for the content object. This globally unique identifier is associated with a metadata source, which enables routing of a user to the metadata source.
