Abstract
A backup volatile state retention circuit is provided with low leakage current for employment with a volatile memory circuit to store the value of the latter during power down of the volatile circuit or during power-down or inactivation of neighboring or peripheral circuits or due to the loss of power of any of these circuits. An example of such a volatile circuit is a memory circuit having volatile memory cells such as employed in dynamic memory core, in particular, a random access memory (RAM) in CMOS circuitry.
