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. Complementary embodiments include updating the compressed count based upon a random number or upon the actual count matching a multiple of the fixed number. These techniques also have application to monitoring other types of recurring events in flash memory systems or in other types of electronic systems. In another aspect of the present invention, provisions are made to maintain an accurate experience count if the memory system experiences an improper shutdown, for example in case of power loss or removal of a memory card.

A gasket system for sealed interfaces utilizes a carrier ring having inner and outer compression stops to account for and control flange rotation effects in order to achieve a uniform and constant gasket seating stress across the sealing region. The inner compression stop provides a fixed fulcrum for flange rotation. The inner and outer compression stops have different heights, dependent upon the characteristic flange rotation, that allow the orientation of the sealing material to be angularly matched to the flange side profile and that allow the sealing material to be fully captured within the sealing region upon full compression, minimizing creep relaxation. A visual compression indicator on the circumference of the carrier ring permits assembly of the interface without the use of specialized or calibrated tools.
