20080222361	PIPELINED TAG AND INFORMATION ARRAY ACCESS WITH SPECULATIVE RETRIEVAL OF TAG THAT CORRESPONDS TO INFORMATION ACCESS - A cache design is described in which corresponding accesses to tag and information arrays are phased in time, and in which tags are retrieved (typically speculatively) from a tag array without benefit of an effective address calculation subsequently used for a corresponding retrieval from an information array. In some exploitations, such a design may allow cycle times (and throughput) of a memory subsystem to more closely match demands of some processor and computation system architectures. In some cases, phased access can be described as pipelined tag and information array access, though strictly speaking, indexing into the information array need not depend on results of the tag array access. Our techniques seek to allow early (indeed speculative) retrieval from the tag array without delays that would otherwise be associated with calculation of an effective address eventually employed for a corresponding retrieval from the information array. Speculation can be resolved using the eventually calculated effective address or using separate functionality. In some embodiments, we use calculated effective addresses for way selection based on tags retrieved from the tag array.	09-11-2008
20110307769	ERROR DETECTION IN A CONTENT ADDRESSABLE MEMORY (CAM) AND METHOD OF OPERATION - A method for accessing a content addressable memory (CAM) system having a CAM and random access memory (RAM) includes providing comparand data to the CAM, comparing the comparand data to entries of the CAM to determine a matching CAM entry and asserting a match signal corresponding to the matching CAM entry. In response to asserting the match signal, the method further includes providing output data, an output parity bit, and an output complement parity bit from the RAM, using the comparand data to generate a generated parity bit, and providing an error indicator based on the generated parity bit, the output parity bit, and the output complement parity bit. The error indicator may indicate an error when the generated parity bit is not equal to the output parity bit or when the output parity bit is equal to the output complement parity bit.	12-15-2011

20100306221	EXTENDING RANDOM NUMBER SUMMATION AS AN ORDER-PRESERVING ENCRYPTION SCHEME - A method and system for cryptographically indexing, searching for, and retrieving documents is provided. In some embodiments, an encryption system is provided that generates a document index that allows users to retrieve documents by performing encrypted queries for keywords associated with the documents. In some embodiments, each keyword maps to the same number of encrypted document identifiers. In some embodiments, an extractor graph is employed to map an indication of each keyword to a number of buckets storing encrypted document identifiers. In some embodiments, an order-preserving encryption system is provided. The encryption system uses an ordered index that maps encrypted instances of ordered attribute values to documents that are associated with those values. The ordered index enables queries containing query operators that rely on order, such as less than (“<”) or greater than (“>”), to be successfully performed on encrypted attribute values.	12-02-2010

20080282091	Systems and Methods of Securing Resources Through Passwords - Disclosed is a method of authorizing access to an item that maintains a lockout count and blocks access to the item if the lockout count exceeds a predetermined value. One feature is that the invention “variably” increments the lockout count if the presented password fails to exactly match the stored password. In this process the invention increments the lockout count different amounts depending upon how closely the presented password matches the stored password. The invention also provides a methodology that allocates a plurality of the same passwords to a plurality of users who share the same userid. The invention allows continuous operation of the item being accessed by providing that each of the passwords has a different expiration date. Also, when dealing with situations where a plurality of users who share the same userid also share the same password, the invention maps information associated with the users to the password in a data file and periodically updates the data file.	11-13-2008
