The present invention provides systems and methods for obtaining information from a networked system utilizing a distributed web crawler. The distributed nature of clients of a server is leveraged to provide fast and accurate web crawling data. Information gathered by a server's web crawler is compared to data retrieved by clients of the server to update the crawler's data. In one instance of the present invention, data comparison is achieved by utilizing information disseminated via a search engine results page. In another instance of the present invention, data validation is accomplished by client dictionaries, emanating from a server, that summarize web crawler data. The present invention also facilitates data analysis by providing a means to resist spoofing of a web crawler to increase data accuracy.

An improved flash EEPROM memory-based storage subsystem includes one or more flash memory arrays, each with three data registers and a controller circuit. During a flash program operation, one data register is used to control the program operation, a second register is used to hold the target data value, and a third register is used to load the next sector's data. Subsequent to a flash program operation, a sector's data are read from a flash array into the first data register and compared to the target data stored in the second register. When the data is verified good, the data from the third register is copied into the first and second registers for the next program operation. This creates an improved performance system that doesn't suffer data transfer latency during program operations that require data verification after the program operation is complete. Alternate embodiments perform the comparison using two register implementations and a single register implementations. The post-writer verification can be repeated and use different bias conditions for reading the data. The process can be automatic or executed by command that can specify the read conditions.
