US Patent 7542333 Logic cell protected against random events

A memory cell stores information in the form of a first logic level and a second logic level that are complementary to each other. The memory cell includes a first storage circuit and a second storage circuit for storing the first logic level and the second logic level. The first and second storage circuits each have a respective input and output. An isolation circuit provides electrical isolation of the input of the first storage device from the output of the second storage device, except during access to the first and second storage circuits.
