Patent TW-525177-B (TW)
Title: Compressed event counting technique and application to a flash memory system
Inventor: MOKHLESI NIMA
IPC: G06F12/16
Filed: 2001-09-10
Granted: 2003-03-21
Abstract: A non-volatile flash memory system counts the occurrences of an event, such as the number of times that individual blocks have been erased and rewritten, by updating a compressed count only once for the occurrence of a large number of such events. A random or pseudo-random number generator outputs a new number in response to individual occurrences of the event, and updates the compressed count when an output of the random number generator matches a predetermined number. The probability of the predetermined number being generated by the random number generator in response to a single event may be varied as the function of some other factor, such as the value of the compressed count, when that provides more useful tracking of the number of events. These techniques also have application to monitoring other types of recurring events in flash memory systems or in other types of electronic systems.

The container integrally extends a backflow channel having two ends respectively communicated with the upper part and bottom part of the container, thereby forming a circulation type circulating flow system. The container contains suitable amount of non-transparent liquid and is filled with gas to provide a saturation state. In testing, minute gas is guided into the air inlet tube of the container for being entered into the liquid to form bubbles. When the bubbles rise gradually in the liquid and pass through the detection channel, the sensor detects the number of passed bubbles and outputs the same to a recorder, so as to compute the amount of minute gas guided to pass through the detector in a period of time, thereby providing the advantage and function of fast, conveniently and precisely computing the detected amount of minute gas in the detection process.
