Autoclave sterilization is suited for objects that can tolerate humidity, high pressure (1 to 3.5 atmospheres above ambient), and high temperature (+121°C to +148°C). Typical examples are surgical instruments. Semiconductor devices usually can handle up to +125°C. However, exposing embedded batteries to high temperature significantly reduces their lifetime. Memory devices that use floating-gate technology, such as EEPROMs, can be sensitive to high temperatures. Loss of data integrity should not, however, be expected if the data retention is specified as 10 years at +125°C. Otherwise one should occasionally refresh (rewrite) the memory data to restore the full charge on the floating gates. This works for laser-trimmed EEPROMs. Since the type of trim is usually not specified in product data sheets, it may be necessary to contact the vendor for details.
