摘要
There is disclosed a volatile electronic counter wherein the count is retained over power off periods. This is accomplished by the use of a non-volatile memory with means for rapidly writing therein the contents of the volatile memory upon sensing a power down condition. Upon later sensing a power up condition, the contents of the non-volatile memory are returned to the volatile memory.
